Not to worry, I hope to be asleep long before that!
Attached find some patches. I've edited out some of the worst crap that
should not be admitted to in public.
DefaultLifestyleManager and PooledLifestyleHander -- this code was broken.
Turns out that the attempt to get the pool setup from inside the
PooledLifestyleHandler constructor caused a self-call which wanted to
print a log message. Tough when enableLogging() hasn't been called yet.
Moved the pool setup to (new method) initialize(). Obvious fix.
The rest is just trying to push errors into sight. The error stuff has
no 'finished product' polish, I still haven't stumbled on where the
error formatting is coming from.
Apologies in advance if I've got Avalon style problems, I just
discovered that netbeans has a nasty habit of reformatting stuff.
Uggh. I think I fixed most of the disasters!
Pick and choose as desired.
Good night...
Gary
