The fix for
JBCACHE-1192 has introduced a couple of problems that are manifesting themselves in numerous errors in the test suite:
1) _gravitateData changes the value of skipDataGravitation for the Option associated with the call, but then doesn't restore the correct value to that instance of Option.
2) _gravitateData calls get(Fqn), and that call actually results in the instance of Option that is associated with the thread being changed (see impl of get(Fqn). But, _gravitateData does not restore the original Option to the thread. Maybe not a problem if _gravitateData is called remotely, since there is no meaningful Option associated with the thread. But _gravitateData can now also be called by DataGravitationInterceptor.localBackupGet, and in that case there very well could be a meaningful Option associated with the thread, and it needs to be restored before _gravitateData returns.
I'll attach a possible patch in a minute.
