What format is your attachement in?  When I try to follow the link, it
asks me to open a file named "showattachment" with no suffix.  It
doesn't appear to be text.

Does your fix do anything for bug 9077?  I've been working on fixing the
patch that is already pending for 9077.

Your timing is good to bring this up.  We should definitely compare
notes.  Last night I committed a patch to JBoss that deals with this
issue (classes can be found in the JBoss CVS in the
org.jboss.web.catalina.tc4 package; most are in the authenticator

The JBoss patch is really more properly a Tomcat patch, but the JBoss
folks asked me to commit it.  I was planning to post a version to the
Tomcat Bugzilla this weekend.  In fact, I'll do it (against Bug 23881)
as soon as I send this.  The TC patch is against TC 5 HEAD; the JBoss
version is against TC 4.1, plus has some minor tweaks to optimize for
embedding in JBoss.
