Sorry for the delay. Yes, you are correct. On a failure, I
don't get that log message.

I have managed to catch it in the act with an eclipse
debugger attached to the process. Given the text and format of
the fatal log message, I put in a breakpoint in line 128 of, where the general Exception is
caught in provisionGroups(). Unfortunately, by the time it gets
to this point, most of the useful context of what is was doing
is gone. The exception it's catching, however, looks very odd.

It's a NullPointerException, but the detailMessage and
stackTrace for the exception are both null. And the cause is
another, similar NullPointerException with null detailMessage &
stackTrace & cause that's a NullPointerException, etc. ad

I'll keep poking and see if I can find a better breakpoint.
