NetBeans IDE processes do not terminate, and cannot be cancelled.

[BruceKHaddon]

Apache NetBeans version

Apache NetBeans 17

What happened

On any execution of a project (run, debug, javadoc) the process does not end. The only way to end the processes is to close the IDE.

How to reproduce

Compile and run anything.

This problem was not present in NetBeans 15 but was/is present in NetBeans 16 and 17

Did this work correctly in an earlier version?

Apache NetBeans 15

Operating System

Windows 10 Pro, version 21H2, build 19044-2694, Intel i7 x64 16.0 GB

JDK

openjdk-19.0.1_windows-x64_bin.zip

Apache NetBeans packaging

Apache NetBeans provided installer

Anything else

Every time.

Are you willing to submit a pull request?

No

[mbien]

what is the exception?

[Chris2011]

I also notice that for "Refreshing status" and "Background scanning". Funny is that it finishes when we kill the IDE, but not the normal cancel process.

[BruceKHaddon]

Michael,

There is no exception. The processes just keep adding up as they are run, and when the attempt is made to select and cancel them, nothing happens when clicking on the x (the entry does not go away, and the process is still there).

The only way to terminate those processes is to exit NetBeans, then answer the question (twice) of do you want to terminate these processes.

Regards, Bruce

I mainly asked since I see a red error notification on the screenshot you posted.

What happens if you kill your program by pressing the stop button in the output window?

[BruceKHaddon]

Michael,

That red error notification is the one from the other report submitted (the one with the “unexpected error”) for which I forwarded the log file.

Clearing that notification has no effect on the “processes-still-running” issue.

Regards, Bruce

BTW, do you have idea of when the copy-and-paste issue will be fixed. I teach and am forever attempting to copy snippets from code to emails and other documentation, or the other round, or trying to copy-and-paste class files from one project to another (the workaround for this last one is to use “Copy” in “Refactor”). Copy-and-paste of code within NetBeans is OK.

i see, thanks, so you say stopping your program via the stop button on the output window does also not work?

off topic: regarding copy and paste

regarding the copy and paste issue: we don't have enough contributors who use windows, I don't even have windows installed anywhere right now. This issue is also not always reproducible - so I can't really say when someone will start another attempt to fix it. but going through old mails, e.g https://lists.apache.org/thread/0r9qm9rkmvl6nxs5zcyr4145xrfwbbq3 you could try setting: `-J-Dorg.netbeans.NbClipboard.level=FINEST` or `-J-Dnetbeans.slow.system.clipboard.hack=false ` or `-J-DTopSecurityManager.disable=true` to your netbeans.conf and check if it has any effect.

[lkishalmi]

Sad but true, the best workaround for the Copy+Paste issue is not using Windows.

[BruceKHaddon]

Dear Laszio,

Not a solution.

I teach, and 99% of my students use a Windows-based laptop.

I sometimes get a student using a Mac (with MacOS) and only one time in a decade have I had a student using Linux on a desktop machine. This is because students are both beginners, and quite usually of very modest means. Students also take other courses, where the tools and programs they need are Windows-based so there is no way for me to ask students to acquire another machine, and learn to use some Unix-derived system (that takes more understanding than they have when starting in the computing world).

So, by saying, “not using Windows,” is virtually equivalent to saying, “don’t use NetBeans.” Do not get me wrong. I have used many IDE’s, and in fact at one time was an evangelist for NetBeans when employed by Sun Microsystems. It is probably the easiest to learn of all the “industrial grade” IDEs. (But even working for Sun, the “enemy” of Microsoft, demonstrations of NetBeans were most often made on Windows machines, at the request of potential customers—who may have been only later converted to Solaris.)

So, the copy-and-paste problems cannot be regarded as a non-issue by dismissing the world’s use of Windows! I regard such a suggestion as being unresponsive. You may have intended the response to be humor, but it is a serious problem for serious users (and probably future proponents of the use) of NetBeans.

Regards, Bruce K. Haddon

p.s. Why is Windows the problem? I have many other applications that work quite well using copy-and-paste on Windows, and I also have Java applications of my own that use the JDK copy-and-paste software, and they also work exactly as expected. Is NetBeans trying to do something clever (like caching) with copy-and-paste? It really is a mystery (and it is a more recent phenomenon).

@BruceKHaddon I don't think the "switch to linux/mac" was actually meant seriously (but please switch to linux :)). Point is: nobody of us uses it which means the motivation is low to fix this and there are extra steps involved to even reproduce it.

NB is developed in the open and relies on contributions, any dev on windows can take a look at it and open a PR. I also linked a thread where users/devs tried narrow down the problem and recommended JVM options. So have you tried those?

Also, lets not derail this issue completely. This issue is not about copy and paste.

[lkishalmi]

Well, I've said workaround and sad. Members of the team put considerable amount of time/effort, trying to figure out how to fix that. We have failed so far.

Surprisingly adding: -J-Dorg.netbeans.NbClipboard.level=FINEST to the command line was the most stable way to avoid the problem. I guess it's a weird timing issue between the OS and the JVM.

[BruceKHaddon]

Laszlo,

My apologies. I guess I am sensitive to the Windows/Non-Windows issue.

As mentioned, I worked for Sun in various roles, mostly customer-facing, and consequently as a matter of course had to use Windows, although I did have Solaris as an alternative boot on my laptop (rarely used). This was at a time when the official Sun (McNealy) policy was that having Windows on a Sun-provided machine was (theoretically) a firing offense. Prior to working for Sun, I had used Windows, VAX VMS, Solaris, Unix 7, IBM OS, plus at least 4 OS’s that I had written or supported myself (as well as several other lesser-known operating systems), so apart from the convenience these days of using Windows and the needs of my students, I am reasonably agnostic to the debates, other than getting annoyed when getting mixed into such debating situations.

Anyway, I shall try the command line suggestion.

Thanks for the support,

Bruce

With the risk of taking this further off-topic, this is not entirely true! I'm certainly motivated to fix, both for NetBeans and platform applications, and have tried to look at and reproduce this on numerous occasions. I have never managed to reproduce following any of the steps outlined. Any dev on Windows looking and opening a PR isn't realistic right now. @BruceKHaddon let's continue and follow up on the dev@ list or on #3962

[neilcsmith-net]

Which build system are you using? I see the exit dialog after building or running Gradle projects on Linux. But only once, and I don't see the progress handles still active during use of the IDE. I suspect this might be partly caused by the Gradle daemon process(es) but I haven't managed to confirm that completely - killing the Gradle daemon does sometimes stop the dialog from appearing.

[ibrayock]

I have the same issue with both Netbeans 17 & 18. Any update on this issue ? Thanks

[BruceKHaddon]

Yes, indeed. This issue causes me to have to reboot NetBeans after about 20-30 invocations of build, clean and build, run, or debug. Even if a process is manually terminated, it stops running, out the process still exists and is listed when NetBeans is closed.

I have students using NetBeans. I cannot explain this behavior to them. This is in urgent need of fixing.

On a similar note, the reported problems with copy and paste are also a problem for students. If I give them a snippet to use, they cannot copy and paste that into any project, nor can they copy and paste a snippet to email me with a question. I have other Java programs (of my own) that use the clipboard, and they work. The problem appears to lie completely with NetBeans.

I am not using Netbeans as a student but for an application based on Netbeans Platform. Any update would be more than welcome.

[neilcsmith-net]

@BruceKHaddon @ibrayock this issue is still labelled pending-response because a number of questions that have been asked have not been answered as yet.

[ibrayock]

i see, thanks, so you say stopping your program via the stop button on the output window does also not work?

off topic: regarding copy and paste

The stop button is closing the running application but the process is still running. Clicking the stop button is not killing them even though it is closing the application. @neilcsmith-net I don't see any other unanswered question beside the one above

[Chris2011]

What about this one? @ibrayock

[Chris2011]

My two cents here, sometimes the cancel button works, sometimes not. Doesn't matter what I did. Sometimes it is the Background Scanning progress. Sometimes it is the Git Refresh Indices and sometimes others. All of them shows the dialog "You will be canceling it, do you want to?" And when I hit cancel sometimes nothing happens. I didn't dive deep into it but the only solution for me was just restart NetBeans and hoping that this is not coming back again. If it is a fresh start from my Laptop everything works fine, after hours work working than it happens. I will try to find more info for it.

For me, the stop button is never working. I have to close Netbeans and start again

[neilcsmith-net]

@ibrayock OK, as you said you're using the platform I suspect it's still related to https://lists.apache.org/thread/6l3tg4brq4522gcmc956jjtj855p6710 Do you have the JavaFX support enabled in Tools / Plugins, or are you running the IDE on a JDK with that included? Also try excluding the html4j libraries from the platform application.

I'm not sure if this is the same as the original report, as it's very RCP specific.

[BruceKHaddon]

Folks,

If it helps, my configuration is:

Product Version: Apache NetBeans IDE 17 Java: 19.0.1; OpenJDK 64-Bit Server VM 19.0.1+10-21 Runtime: OpenJDK Runtime Environment 19.0.1+10-21 System: Windows 10 version 10.0 running on amd64; UTF-8; en_US (nb) User directory: C:\Users\bkh\AppData\Roaming\NetBeans\17 Cache directory: C:\Users\bkh\AppData\Local\NetBeans\Cache\17

The problem of a process not terminating is seen whether JavaFX is enabled or not.

When a compile or running program terminates, the progress bar stops showing "progress", but a running process remains.

It is possible to cause an executing compile or running program by use of the the X button on the progress bar (bottom right), and get the pop-up asking whether you want to cancel, and with a Yes answer, the execution stops, but there is still left a running process.

When NetBeans is closed, the warning of these running processes appears in a pop-up with the processes listed. If the "Exit IDE" button is used, the NetBeans window disappears, but leaves another pop-up with a repeat of the same request, see below.

@BruceKHaddon there are at least 3 possible build systems in NetBeans for Java (and I'm assuming these are Java projects). Please confirm what build system you're using, and ideally share one of the projects to this issue, as well as how it was created (wizard type, etc.). Also check View / IDE log and see if there's anything peculiar in there when the processes are stuck. Thanks!

[BruceKHaddon]

Neil,

The build system is Ant.

The most recent log files are attached (what is "peculiar" in this context).

I have a number of projects where I run the compiled classes as programs outside the IDE. These terminate quite normally.

Doesn't matter what I did. Sometimes it is the Background Scanning progress. Sometimes it is the Git Refresh Indices and sometimes others. ... And when I hit cancel sometimes nothing happens.

well this isn't useful since those task have completely different implementations. The task has to support cancellation. The button is just a button which tells the task to cancel. Cancelling a thread is always a best effort situation, you can interrupt it if it is blocking on IO or locks and when its not you hope that it runs into the next if (cancelled) return check. Thats it.

Cancelling a process, like a different JVM is again a completely different situation. So please be concrete here or nobody will be able to investigate this issue.

public class Mavenproject2 {

    public static void main(String[] args) {
        JFrame frame = new JFrame();
        frame.setSize(200, 200);
        frame.setVisible(true);
    }
}

I ran this on linux as maven project on NB 18/JDK 20, pressed the stop button, closed NetBeans and everything shut down no questions asked.

[mbien]

The build system is Ant.

thanks. just repeated the same test above in an ant project and it did work too. Is this a windows specific issue?

I also tried to stop it in a debugging session while it is on a break point, that worked too.

@BruceKHaddon I cannot replicate with either the ASF or Codelerity (community) installer using the default Ant project on Windows 11. That's why the logs or actual project might be useful. You can attach files to issues and comments in the GitHub UI. You can't do it via email, and please don't reply to issues via email as it spams comments with a lot of useless text.

Can you also see if the community installer works for you. That bundles a local JDK for the IDE, and I'm curious whether that also replicates what you're seeing on your system.

[ibrayock]

@ibrayock OK, as you said you're using the platform I suspect it's still related to https://lists.apache.org/thread/6l3tg4brq4522gcmc956jjtj855p6710 Do you have the JavaFX support enabled in Tools / Plugins, or are you running the IDE on a JDK with that included?

I didn't have JavaFx support enabled in Tools / Plugins. I enabled it but still the same issue. I am using openJDK 17.0.7 with JavaFx included. There is no html4j dependency on my platform application. The issue is still existing

Thanks

[neilcsmith-net]

@ibrayock have you specifically excluded html4j from the platform as covered in that thread?

[ibrayock]

@neilcsmith-net Executing a dep tree with maven or looking under "Dependencies" drop-down list on Netbeans doesn't show any html4j dependency so I don't know where to exclude it since it's not there in the first place.

[BruceKHaddon]

1060_01_ZAHelloWorld.zip messages.log messages.1.log messages.2.log

Here are the files that I tried to send by email (cannot use email in the 21st century?) The zip file is a Netbeans export file with just a "Hello, World" program. On my machine, it has the same behavior as all other projects (processes not terminating completely).

[neilcsmith-net]

@BruceKHaddon looking at the log I suspect this might be related to #5633 given the stack trace of that error in your log. There are lots of other messages around the classpath that seem suspect too. Have you tried the suggestion from that issue and deleted the userdir and cachedir (or renamed if you want to backup the configuration)?

[neilcsmith-net]

@BruceKHaddon you could also take a look at https://github.com/apache/netbeans/issues/6076#issuecomment-1593391874 and whether following that process fixes things for you.

[BruceKHaddon]

Michael,

Thank you for finding (and fixing) this problem (I have been restarting NetBeans 4 or 5 times a day to clean up non-terminating processes).

Have you any idea which release will have this bug-fix included?

Regards Bruce

the change does not fix the root of the issue since it is not known how the config files are getting corrupted on windows. It adds defensive measures to prevent the import of corrupted files into the next NB version and handles property files with invalid keys a bit better in some cases.

But to answer the question: the change should be in NB 19

You could reset the netbeans config which should fix this issue too.
