[rules-users] Use of KnowledgeAgent in JEE Container

I was wondering if it's safe to use the KnowledgeAgent inside of a JEE container. I'm assuming that the KnowledgeAgent implementation spawns a thread to poll for changed resources (to reinitialize a KnowledgeBase, for instance, when updated DRL files are detected). Normally, use of unmanaged threads is considered a no-no inside of a JEE container. Has anyone encountered any problems with this? Dave
