Hi Dave, have you got the classpath for this webapp set to parent last?
The code that consumes the exception is intended to cache the exception in
the Monitor for later analysis by the runtime. This happens in various
places now but obviously we have to be careful that this doesn't have any
adverse effects to subsequent processing. This must be a case that we didn't
get right so we need to fix it as the intention isn;t to just swallow the
excetion silently.
Regards
Simon
