Bulk actions fail with Error 500, java.lang.IncompatibleClassChangeError

Maybe duplicate of JRA-39757, but the security setting does not let me read it, somehow google can.

Problem: Since the update of Jira to 6.3.4 bulk actions (edit, move, transition) fail and report a 500 Server error with the following stacktrace.

This Stackoverflow thread tells me, that it is nothing which i can fix, but correct me if i am wrong.
