Hi, In 5.3 we saw a Jitting problem (as a result of the same rule getting 20 times and Drools attempting to compile a new object for performance). We were recommended to move to 5.4 rc 1 to fix the issue (which it did). We were about to migrate today to 5.4 Final and noticed that people have identified that the same Jitting error is back. https://issues.jboss.org/browse/JBRULES-3511 The fix has been pushed to the master branch. I was wondering what the timescales were for this to be released as 5.4.x? In the mean-time should we stick with 5.4 rc 1 or move to 5.4 final and merge with the fixed files in GitHub https://github.com/droolsjbpm/drools/commit/75c6efb7ddfc197436a687cb594b2...
