We just upgrade to JBoss 2.4.1 and now we are getting principal = null exceptions. We found that it has to do with a boolean inside the JBoss security classes and that we can use a static initializer to keep the class from using the boolean. However, we were curious if there is an inteded method for setting the thread safe access to the principal. thanks, d. _______________________________________________ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user
