I'm not very savvy about server cache and Drools. You pretty much got
my best idea which is to try to diagnose the problem.
Perhaps someone here who has experience with Tomcat and Spring will
have an idea of what is going on.
p.s. I suspect your chances of getting a more qualified responder would
have been much improved if you had described the full context of your
problem in the original post.

In the mean time, can you explain when I deploy a new .drl file,
packaged within a jar file, as part of my web application why/how a
compiled version of the old rules might be picked up? I understood up
to this point that when I deployed the new .drl file, restarted my
application in Tomcat, and via Spring re-initialized my service that
lazy initializes the RuleBase that the new rules would be picked up
from the file in the classpath, not a different compiled version. Is
the compiled version (i.e., the previous version of the .drl file)
serialized or cached on the server somewhere?
I've been confused as to how the old rule was firing after I verified
that it no longer existed in the new .drl file that was redeployed to
Tomcat. How can I prevent a previously compiled version from being
used? I definitely don't want that to happen. The only thing that
fixed this problem for me was restarting Tomcat, which isn't
practical, of course, in our production environment.
