This bug was originally marked as duplicate of bug 246934, that is already resolved. This bug is still valid, so this seems to be another bug, but it might be related.

Trying to figure out if this is the bug which is causing the IDE to become barely usable for running tests in CoS mode: every time I try to do so, I get an error about some class missing a code attribute on a method. I think this is due to broken classpath scanning. Running a Maven clean build does not help, because cleaning generated sources triggers new IDE scanning that I cannot suppress, which overwrites valid class files with junk. Closing the project(s) and then running a clean build from an external shell allows me to use the right class files, but then makes the CoS part not work at all.

Does seem to be associated with broken CoS testing. Makes dev builds unsuitable for working on Jenkins core.
Tried deleting my cache. Now I do not seem to get this; I get #200970 instead. I suppose that is an improvement.
Got this again even after having deleted my cache recently, so it is not attributable merely to having ancient and broken class files lying around. BTW the code triggering this seems to be github.com/jenkinsci/jenkins/core/src/main/java/jenkins/security/s2m/OpMatcher.java: interface OpMatcher { boolean matches(String op); OpMatcher ALL = new OpMatcher() { @Override public boolean matches(String op) { return true; } }; }

Last I checked this was consistently reproducible just by checking out github.com/jenkinsci/jenkins and opening all the modules.
