Tests in the Plugin Tests project fail

[DelusionalLogic]

Hey,

It looks like commit 26188a9eda2d7b7345648d06bbe5c13c3096e793 has caused a regression that breaks the build. I got the commit by bisecting. This is the relevant part of the build log.

It appears as if your JDK does not supply a working agent attachment mechanism.

I'm open to provide more details, but I don't know what you'd need.

Hmm..

I haven't a Linux machine. But on my Mac and Windows, the build has no problem.

The CI builds run successfully as well on all three platforms: https://github.com/microsoft/vscode-java-test/actions/runs/6452491660

I didn't have the jdk correctly installed. I don't understand why how it was working in the older revision, but I'm satisfied that it's my bad.

Thanks a bunch for looking into it, and sorry for wasting your time :)

Hi @DelusionalLogic, would you mind sharing the 'correct' JDK you have installed to fix the issue? In case other people meet this problem, that might help :)

Thank you!

[DelusionalLogic]

It was literally just any JDK. I had installed the 17 JRE, not the JDK. A complete blunder. I don't understand how it was even able to compile with that, but it must have been something with how arch linux packages java.

I started off downloading Zulu (what you use on CI), and when that worked I started to examine why. Turns out I had just installed jre17-openjdk instead of jdk17-openjdk from the arch repo.

Again, really sorry for wasting your time.

Thank you for sharing :)
