Yes, I get this as well. It is because this patch. There is another
problem, when I fix the NPE, my program hangs or complains about Bad
Allocation when getMinimumSize is called. The exact error message is:
"The error was 'BadAlloc (insufficient resources for operation)'". There
might be another loop somewhere.
