Hi folks,
I've been having a peek at the Tomcat main CVS branch in respect of its classloading
behaviour. Apologies if I have missed any discussion - I have only just subscribed,
and I did not find much in the tomcat-dev archives a couple of days ago.
It appears to me that ClassLoading is

Hi David,
Thanks for this report, I'm impressed on your deep understanding of the
subject. Class loading is one of the most difficult areas, and until Nacho
implemented most of the new loader scheme we had lots of problems. ( that
happened few months ago ).

pass the entire Filter Chain, so a request that takes longer to be
served simply occupies the server thread more than necesssary ,

explain your objection.
