[Opensource] cache="n" ?

 I changed the <jdbc> definition in expresso-config.xml that applies to the default hsql db to have attribute cache="n" .  in other words, I turned the database/object cache off.

I got a stack overflow (below) in Setup.java when starting up.

can you duplicate this result?   is this particular to my setup (cvs head from a couple weeks ago), or an ugly bug?  the JVM has plenty of RAM via -Xms128m
