Thanks for the response, Marc.
I have proceeded to the point where, with the default settings,
everything boots up until the InstantDB blocks on a pool call. At this
point, JBoss is frozen. The log tail looks like this:
[Hypersonic] Started

If I change Blocking=false in jboss.jcml then I get NPE's like this, but
the server continues to boot. However, JBoss seems non-functional at
this point as it does not recognize anything dropped into the deploy
directory:

I'm not sure how to debug this further since I don't really know what's
going on. I saw what looked like a related post, but there were no
followups.
Any further help is appreciated. My sample code is available upon request.
Thanks,
Stewart
