Richard S. Hall commented on FELIX-3939:
----------------------------------------
I think what we can do in this instance is simply catch the IAE since it
appears that the race condition is harmless. Subsequent calls will correctly
see that getPackage() returns non-null and won't continue to get exceptions,
only the losers of racing threads will, which if we catch and swallow, then no
one has to know.
