While working on 2019-06 error is logging frequently. I have been using the eclipse committer package for the past 20 days. But, It did not happen earlier.

Comment 1 Stephan Herrmann

This indeed looks like you have a corrupt class file org/eclipse/jdt/internal/core/search/BasicSearchEngine$6.class

Is this using the original plugin org.eclipse.jdt.core_3.18.0.v20190522-0428 ?

Did you install any plugin that uses "JDT Weaving"? (e.g., AJDT, ScalaIDE ...)

If all looks pristine on your side, please attach the class file in question (extracted from plugins/org.eclipse.jdt.core_3.18.0.v20190522-0428.jar).

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
