Hi everybody,

I have a few Wonder applications that were deployed with Maven recently which seem to be crashing randomly.  Some are of these applications are completely new, but others have been running for years (deployed with ANT) without such problem.  The stacktrace looks like this:

21951 [main] WARN NSLog  - A fatal exception occurred: null
[2013-7-29 14:59:28 EDT] <main> java.lang.NullPointerException

I have tried many different things but I cannot find a solution.  This is driving me NUTS!  Hints anyone?

Thank you.

Martin
