[rules-users] unable to determine value type class *** URGENT***

   Ok, I saw this problem raised a couple times and it seems to be related
with the JVM, not really the app server. It is a classloader problem.

   Unfortunately, I could not reproduce this in my environment, so if anyone
capable of reproducing the problem is willing to work with me on this, we
can look for a solution. First of all, I need the complete stack trace of
the problem, as well as drools version, mvel version, complete JVM version
and revision. Then, it would be good if you can isolate the problem in a
small test case, otherwise we will have to go without it for now.

   Having that information, I will try to make some code changes and send
you and see what happens.

   Thank you,
       Edson
