[rfelcman]

Just one note about code styling. Please reformat it into stlyle like #1843
e.g.

if () {
}

instead of

if ()
{
}

Thank You

I've corrected the formatting. I accidentally used the wrong auto-formatting.

@rfelcman Can you have a look at the checks which seem to fail because of a build environment issue?
/home/runner/work/eclipselink/eclipselink/antbuild.xml:455: Maven 3 not found. Build won't run if Maven 3 not installed and M2_HOME properly set!.

There also seems to be a problem with the Jenkins-Builds: The builds for the PR are waiting for the nightly-build to complete, which seems to be stuck in a loop with the error message kubernetes resource quota exceeded.

I know. Fix for this issue is part of #1859

I see I restarted it (https://ci.eclipse.org/eclipselink/job/eclipselink-pull-request-verifier/job/PR-1860) manually.

Hi @rfelcman,
2 months later and after 4.0.2 has been released with the fix - is there already an ETA for a new 2.7 release?

[rfelcman]

About next 2.7.13 there is no any ETA yet.

[patric-r]

@rfelcman 3 months have now passed.
As you estimated "1-3 months" for a new 2.7.x release since the fix, we're now looking forward towards a new release on short-term in order to benefit from our contribution.
