Fernando commented on TAPESTRY-2316:
------------------------------------
Actually. We've also seen this, but since I couldn't get a feeling of what is
wrong I didn't follow up sorry.
(I was afraid that maybe us overriding the Exception handler or something
else..)
Our environment was Jetty 5, Jetty 6, JDO 1.5, Ubuntu; so I don't think it's
tied to environment.
Anyone else? have any ideas?

> This code snippet throws the exception. (TapestryModule:535) Thus even if the

> Perhaps the solution would be to wrap this code with an another trycatch
