Clicking a running application causes VisualVM to freeze

L12C commented 2 years ago

Describe the bug Clicking (Both left- and right-clicking) a running local application causes VisualVM to freeze.

To Reproduce This will probably not reproduce it for you, but it's all I did

Open VisualVM
Start other Java Application (from command line)
VisualVM displays the running application
Click the application in the list in VisualVM
VisualVM freezes for ~60 seconds
After VisualVM unfreezes, it shows "Opening (PID ...) in the bottom right corner
A couple of seconds later, it displays an error icon in the bottom right corner

Clicking that icon reveals this error text:

java.lang.NullPointerException: Cannot invoke "java.util.Properties.getProperty(String, String)" because "props" is null

Expected behavior VisualVM should open the view for this running process

Additional context

VisualVM installed from repo (https://archlinux.org/packages/extra/x86_64/visualvm/)

thurka commented 2 years ago

NPE is fixed by GH-368. BTW: You are running VisualVM 2.1, not 2.1.1 as mentioned above.

L12C commented 2 years ago

You're right about the version, I misread the package version which is 2.1-1.

Unfortunately, I wasn't able to build the current master branch to verify this fixes the error

You need to build it with JDK 8. See README.md.

Same issue here, VisualVM hangs as soon as any application is touched.

I with multiple different versions, including current version 2.1.7, jstack produces the following thread-dump

@centic9 Can you provide steps to reproduce it? Thanks.

centic9 commented 1 year ago

It happens consistently when I open visualvm and click on any of the running java processes in the list.

thurka commented 1 year ago

It does not help me much. There must be something specific to your setup, OS, JVM or running java processes. it would be great if you can discover it. Are you able to replicate it in different environment? Like different machnie or under different user?

centic9 commented 1 year ago

Any hint what to look for based on the stack-trace?

I.e. permission handling? JDK version mismatch? Inter-process communication problems? ...

thurka commented 1 year ago

It looks to me like Inter-process communication problem, but it is hard so say. What OS are you using? Can you attach VisualVM log file?

centic9 commented 1 year ago

Sorry for the noise. After shutting down things one-by-one I found a Java process in a strange state which also did not react to normal kill any more. After removing it via kill -9, visualvm works again.

So a single broken process can break this type of communication for all Java processes on the same machine. :(

Thanks for update.
