@nrmancuso Same error at sevntu-checkstyle/sevntu.checkstyle#1019 .

Hmm, I wasn't expecting a merge commit to be added.

I will fix on my local, you have to manually select rebase in GitHub

Do we know why it becomes a problem unexpectedly?

@romani The jar used for this job was compiled with jdk17, so I assume that eclipse migrated from 11 to 17

Better for us to stay on jdk 11 version and migrate to jdk 17 after summer .

Can we set hardcoded version at

Eclipse is on jdk17 https://wiki.eclipse.org/Eclipse/Installation
Idea is on jdk17 https://intellij-support.jetbrains.com/hc/en-us/articles/206544879-Selecting-the-JDK-version-the-IDE-will-run-under
Sonar still on jdk 11 for scanner (our execution environment): https://docs.sonarqube.org/latest/requirements/prerequisites-and-overview/

We should stay on jdk 11.

We should use R-4.27-202303020300 , it will give us about a year on runway on this version, in a year we will decide what to do.

We should comment out line I pointed to and make new line with hardcoded value.

@romani done
