Trying to open VisualVM outputs following error:

VisualVM log
Version of OpenJDK is not supported. Please use the default-jdk.

Desktop (please complete the following information):

• OS: Ubuntu
• Version 22.04.3 LTS

Additional context
java -version outputs:

openjdk version "17.0.9" 2023-10-17
OpenJDK Runtime Environment (build 17.0.9+9-Ubuntu-122.04)
OpenJDK 64-Bit Server VM (build 17.0.9+9-Ubuntu-122.04, mixed mode, sharing)

and $JAVA_HOME is /usr/lib/jvm/java-17-openjdk-amd64

What version of VisualVM do you use? How you 'open' the VisualVM? Can you please post the whole output from terminal?

[thmasker]

I write visualvm in the terminal, and the whole output is exactly what I put:
Version of OpenJDK is not supported. Please use the default-jdk.

I've tested it with several versions of VisualVM, including 2.06, and the latest: 2.1.7

[thurka]

Can you try visualvm --jdkhome /usr/lib/jvm/java-17-openjdk-amd64?

[thmasker]

I've also tried that. Same error is obtained

[thurka]

Can you try to use absolute path for visualvm?

[thmasker]

you mean like /usr/bin/visualvm --jdkhome /usr/lib/jvm/java-17-openjdk-amd64? Tried it with and without --jdkhome. Same output error

[thurka]

Hmm, this is strange. That error is not part of VisualVM sources. Where did you get VisualVM from? Please try the following:

1. download VisualVM 2.1.7 from https://visualvm.github.io
2. unzip it to /tmp
3. run it with /tmp/visualvm_217/bin/visualvm --jdkhome /usr/lib/jvm/java-17-openjdk-amd64

[thmasker]

Well I'm seeing exactly this error message on /usr/bin/visualvm line 87... Anyway the steps you just gave me worked

[thurka]

Well I'm seeing exactly this error message on /usr/bin/visualvm line 87...

.. but this code does not come from visualvm sources. Where did you get the VisualVM from?

Anyway the steps you just gave me worked.

OK.

[thmasker]

I installed it via apt sudo apt-get install visualvm was literally the command I used

[thurka]

I see. Unfortunately we cannot control what is installed by apt-get install visualvm. This is probably not the original visualvm version and it looks like the visualvm launcher script was modified. If in doubt, please use version from https://visualvm.github.io/
Thanks.

[thmasker]

Ok, then. Thank you!
