[Solved] Concurrency bug in 5.4.0.Final

by Edson Tirelli

Hi all, Just a heads up, in case you are using the community release 5.4.0.Final in a multi-threaded application, be aware that we found a quite serious racing condition bug: https://issues.jboss.org/browse/JBRULES-3573 The bug is now fixed in 5.4.x branch, so I strongly recommend that you build from source and use that instead. The bug was also fixed in the up-stream branch and will be released in 5.5.0. IMPORTANT: if you are a Red Hat subscriber, you don't need to do anything as the problem did not exist in the product release.
