Roughly half the time, when I start VisualVM (1.4.1), the local applications do not show up, and the exception below is caught:

Same here with JDK 11.0.7. I suspect that it could be related with running VirtualBox at same time, or something like that.

This looks really weird. It looks like ServiceLoader.load() is not able to load JDK classes:

sun.jvmstat.perfdata.monitor.protocol.file.MonitoredHostFileService
sun.jvmstat.perfdata.monitor.protocol.local.MonitoredHostLocalService

Are you able to reproduce it? Can you run VisualVM with -J-verbose and attach complete output? Maybe this can provide additional info about this issue.

Verdoso commented 4 years ago

Hello there, It's just happening to me right now and i wanted to add a bit more info:

It's not happening just with local scheme: It's happening to me with "Could not find MonitoredHost for scheme: rmi" and a remote host
With current version (2.0.4) and 3 remote hosts defined it's happening to me 90% of the time. Sometimes local appears, sometimes one remote node appears, sometimes two, but so far I've seen very few times the 3 remote nodes working except when I defined them. I created the connections, all remote applications where showing fine and after closing and starting again, I can seldom get all applications to appear.
The three remote hosts are all defined the same (JDK11, jstatd) and sometimes one appears, sometimes the other, sometimes two of them... so it seems not to be related to the remote hosts themselves or the connection configuration (just hostname specified, everything else default)
The same configuration works fine with VisualVM 1.4.4. I've tried many times and I have not seen it fail a single time. I copied the repository definition from one version to the next, so no differences there.
I have tried setting the JDK to 11 in both versions (1.4.4. was using Java 8) -> 1.4.4 fails.
If I change the 2.0.4 to Java 8, then it starts working, or at least I have not seen it fail
"Could not find MonitoredHost for scheme:" is the message used by Java 11 and not by Java 8, so I would say the problem is Java 11 MonitoredHost class.
The method to find the MonitoredHost is static and is reusing the static monitoredHostServiceLoader variable, its iterator to be precise, without synchronising access... could it be that the iterator returned by ServiceLoader is not threadsafe? Looking at ServiceLoader, it seems it is reusing the iterator and I see no syn code anywhere so...

Given all of that, I would bet my € that the issue is the piece:

        for (MonitoredHostService mhs : monitoredHostServiceLoader) {
            if (mhs.getScheme().equals(hostId.getScheme())) {
                mh = mhs.getMonitoredHost(hostId);
            }
        }

when being run concurrently by all the connections trying to get the MonitoredHost and ServiceLoader lazy initialising the iterator multiple times. Race condition there.

I hope it helps! D.

References: Java 11 MonitoredHost - getMonitoredHost method Java 8 MonitoredHost - getMonitoredHost method Java 11 ServiceLoader - iterator() method

Edited: Java 1.4.4 working with Java 11 was not making sense so I tried again and then all of the connections failed.... so confirmation again that Java 11 seems to be the issue.

Verdoso commented 4 years ago

Hi again,

To validate my theory, I just tested a brute force approach and added synchronized to the two methods in org.graalvm.visualvm.jvmstat.application.JvmstatApplicationProvider that call MonitoredHost.getMonitoredHost(...).

With that simple change, I have not been able to get the error to appear again. If I revert the changes, I get the error 99% of the times I try.

Not recommeding at all that solution, as I said: a brute force test, but it seems to be clear that MonitoredHost.getMonitoredHost is not thread safe so access to it should be synchronised in someway. Salute! D.

thurka commented 4 years ago

Thanks a lot for the investigation. So what are the steps to reproduce it? Does it require to have those remote hosts or are you able to reproduce it only with local java applications? Does it happen only when you start VisualVM?

Verdoso commented 4 years ago

I have been able to reproduce it when I use it with Java 11 and more than one remote connection, so I think just local applications will probably not trigger it. The more remote connections you have, the more probable it is to run into the race condition. With local applications and 3 remote hosts, I run into the issue 9/10 of the times.

It happens to me when I start the the application, as it's the time when the MonitoredHost is tried to load. It might seem, from some comments I have seen, that the application might try later to reload the failiing hosts, but I have not experienced it.

In order to reproduce, simply add 3 or more remote hosts (jstatd connections), just to make sure you run into the race condition, and at first you should see all the apps in those hosts. Close VisualVM, reopen the application and you will see that some remote hosts, or the local one, no longer detect any applications. Master right now displays an exception in the GUI, but 2.0.4 just silently displays an error in the logs.

thurka commented 4 years ago

Thanks. I will try to reproduce it. FYI: 2.0.4 (or any other VisualVM release build) displays the error as a small red circle in the down right corner.

thurka commented 4 years ago

It looks like running VisualVM on JDK 8 is a useful workaround until this issue is fixed.

Verdoso commented 4 years ago

Yeah. I was trying to run it with JDK11 to see if I could get the CPU readings to display when monitoring applications with Java 11, but still getting 'Not supported for this JVM.' I then saw that I was missing the apps in some hosts and fell down the rabbit hole :D

thurka commented 4 years ago

I have really hard time to reproduce it. I am not able to reproduce it on macOS and I was able to reproduce it on Linux, but in one of twenty cases. :-(

Verdoso commented 4 years ago

Well, it might be that I have 20-something applications in each of those hosts and that makes it easier to trigger the race condition as it takes longer to create the full tree, but I see it 9/10 times. VisualVM on W10 against hosts running jstatd on Linux., in case that helps.

thurka commented 4 years ago

The bug is causes by missing synchronization in MonitoredHost.getMonitoredHost(), since javadoc for ServiceLoader states that:

Instances of this class are not safe for use by multiple concurrent threads.

Verdoso commented 4 years ago

Exactly. With Java 8, MonitoredHost.getMonitoredHost() is thread safe as it uses class loading and local variables, Java 11's MonitoredHost.getMonitoredHost() became not thread safe due to using a private static ServiceLoader instance.

cowwoc commented 2 years ago

@thurka Can you please introduce a workaround for this issue? It forces me to restart visualvm on a regular basis. Maybe you could synchronize access to the non-thread-safe method?

thurka commented 2 years ago

The easiest workaround is to run VisualVM on JDK 8.

cowwoc commented 2 years ago

@thurka Which, I assume, is not possible if I am attaching to JDK 18/19...? Isn't it possible to add a workaround into visualvm?

thurka commented 2 years ago

Your assumption is incorrect. VisualVM runs on JDK 8+ and can monitoring JDKs from JDK 6 up to JDK 18. I am trying to avoid workarounds for bugs in JDK and other external libraries as much as possible.

Verdoso commented 2 years ago

@cowwoc The problem happens due to the version executing VisualVM, so it's just that one that you have to change. As @thurka mentions, for this issue it does not matter the VM that you are monitoring, just the one running the VisualVM process.

OTOH, wasn't this already solved? I'm no longer monitoring that many processes through visual VM but I though it had been fixed and was not happening with the latest version of VisualVM. I might have solved it simply by running in JDK 8 or using the patched version... ¯_(ツ)_/¯

cowwoc commented 2 years ago

Running JDK 8 solved it for me, but it definitely still breaks on newer JDKs.

krallus commented 2 months ago

I am having the same issue when running VisualVM on OpenJDK 21.0.4. Note that this appears to have been addressed in OpenJDK 22+ by this commit, but I have not actually tested it.
