As part of testing Tomcat 7.0.35 when I moved to it, I run an Ant script
to pre-compile all our JSP pages.
When doing so I get a huge number of new failures which boil down to the
following stack trace. Any ideas here? I can dig in to try to see
what's causing this, but this is new behavior.
Poking around in the running web app, things seem to work, so the issue
seems specific to using Jasper for pre-compilation.
