I've had this error too running confluence in JBoss, the server.log contains the same stacktrace as pasted above, no other useful information.

I've had it happen when I tried to create a child page 4 levels deep, now the problem is that I can't even remove that page. This always happens, it was not just a once time occurrence, I've tested with other pages too. The thing is that the pages are created but cannot be viewed or removed for some reason.

Some additional information:

running confluence 1.3.2, build 114
Windows XP
JBoss 3.2.5
2 GB RAM
Pentium 4, 2.8GHz

Ps: in my previous comment I meant to say it always happens with pages nested 4 levels deep
