@subyssurendran666 , @mpalat : please check.

@subyssurendran666 , @mpalat : please check. We have M2 this week, it would be nice to have the fix before Thursday.

[carstenartur]

We still cannot run the build without lots of errors.

https://download.eclipse.org/eclipse/downloads/drops4/I20240725-0200/testresults/html/org.eclipse.jdt.ui.tests_ep433I-unit-cen64-gtk3-java17_linux.gtk.x86_64_17.html

Do we have some additional errors now caused by a different issue as before?

[jjohnstn]

I can verify that BindingNamesTest now fails locally. It cannot find X which is a class in the default package. This failure was introduced somewhere after commit f6fe3c8fee3d83b2478db25e where the test works.

[jjohnstn]

I should have clarified that the commit in question is from jdt.core

[iloveeclipse]

Do we have some additional errors now caused by a different issue as before?

Yes, we do, after merging eclipse-jdt/eclipse.jdt.core#2551
I'm working on fixing tests, first batch is #1543

[carstenartur]

I fear removing support for a java version enforces changes in a couple of junit tests in jdt.ui.
In some cases one test for a certain way to process code has been implemented eg in a Java 7 test configuration and another one in Java 8 configuration. Now removing the test for Java 7 is no big deal as this is no longer a valid environment. But the Java 8 based Test configuration might still represent behavior in latest Java versions and should not get lost. Now there is no way to see on a test if it is still representing a valid test case that should be migrated to a Java 17 Test configuration. I guess the Test configuration concept needs a review at least for jdt.ui.

@jjohnstn : could you please check MoveMembersTests fails?

[jjohnstn]

@iloveeclipse I'll check

[jjohnstn]

Both failures are due to using 1.8 which added the ability to have static members in interfaces (fails < 1.8). I'll put together a fix for the test.
