1.43.0 Tests disappeared and "Background task" at 1 % "forever"

[jhberges]

Platform: Windows
JDK: Temurin 21 (also tried 24, just for the heck of it)

Identifier: redhat.java
Version: 1.43.0
Last Updated: 2025-06-27, 09:50:16

Seemed fine to begin with then, after changing code repository I worked on, I noticed that some JUnit tests did not get the "Play" decorations.
Indeed the TestExplorer was empty.

Then after "rebuild" I noticed that the status lines hung on Java Background task - 1 % "forever".

The log for the extension then starts with:

Rolling back to 1.41.1 brought normality back. :-)
And, yes - we use Lombok so 1.42.0 isn't an option to try out.

It seems that the problem is related to annotations on a record class, and it looks like the issue was recently resolved (eclipse-jdt/eclipse.jdt.core#4146).
Since I’m not using Lombok, I reverted to version 1.42.0 and everything is now working perfectly on my end.

[rgrunber]

If it's related to that issue, then it probably just missed making it into 1.43.0. I kicked off a pre-release build for 1.44.0 (it should be v1.44.2025062800). Would you be able to try out the pre-release stream and let me know if it solves the issue ? If so, might be worth doing a bug fix release (1.43.1) for that.

If it's related to that issue, then it probably just missed making it into 1.43.0. I kicked off a pre-release build for 1.44.0 (it should be v1.44.2025062800). Would you be able to try out the pre-release stream and let me know if it solves the issue ? If so, might be worth doing a bug fix release (1.43.1) for that.

@rgrunber > I can confirm that this works as expected:

Identifier   redhat.java
Version      1.44.2025062800
Last Updated 2025-06-30, 07:51:46

Perhaps even snappier than 1.41.1?

I switched to the prerelease 1.44.2025062800 and it fixed the issue for me. Related: #4050 (comment)
Previously, I had to downgrade to 1.41.1 to fix the issue.

I’ve now tested the pre-release version 1.44.2025062800, and everything is working perfectly.
