--------------------------------------------------------------
Question: I'm looking at ContextService.stop(). It looks like the factory
member is accessible after its members are nulled but before the member itself
is nulled. Could this be causing getFactory() to return null rather than throw
a ShutdownException? (I see the fix for DERBY-5088 has a comment expecting
ContextService.getFactory() to possibly fail with a ShutdownException, but not
by returning null.)
