I don't know if you have seen my other post about this, but swallowOutput 
seems to be a little flaky in its implementation.  Although I have it 
enabled for my context, only _some_ of the std out from the context gets 
redirected properly.  I tried searching thru the Tomcat source code to see 
where this magic happens and to see if I can catch where the problem lies, 
but got miserably lost looking at any source that relates to swallowOutput.

So I would tread lightly if wanting to use swallowOutput; I'm not convinced 
that it is working perfectly.
