I have two projects with JUNIT 4 dependency.
Since the 2.6.2 update , i can not open the project in Package explorer view. it stays empty.
In the error log :
Problems occurred when invoking code from plug-in: "org.eclipse.ui.workbench".
java.lang.NullPointerException: Cannot invoke "org.eclipse.jdt.core.IClasspathEntry.getEntryKind()" because "entry" is null

eclipse 4.32, under linux.
I can resolve by removing the JUNIT 4 dependency.
If I add it back the error show up again.
But if I add JUNIT 5 it works
