Other problems with ognl/enhancements

[Martino Piccinato <ma...@gmail.com>]

It seems it's ognl time for us :-)
I send a different messages for this problem because it seems it might
be due to another.

After some time (2/3 hours?) my server is running I keep getting the
exception I copied down here. It seems to be a different one from the
one I reported. It's like javassist can't find his own created classes
so I thought about a PermGen/Memory issue but I have no other evidence
of it that this behaviour.



We are running tapestry 4.1.2
