I'm not a javac expert, but this looks like a fix for a case where expected state (currentMethodSym) could be silently trashed, resulting in a later NPE. The code is tip is more complex, but retains the "restoration of state" idea in this code. Also, the patch includes a test (which passes) derived from the one attached to the original JBS issue.
