Davide Sottara <dsotty> made a comment on jira DROOLS-197 no CCE with 5.6 Lukas, Alessandro, what is the context for this ticket? Is it for 5.3.x or 6.x? If it is for 5, was it reported by a customer and we need to backport the fixes? Just trying to understand what needs to be done here. Just got the e-mail from Alessandro: ============= They should be part of the Roll Up Patch BRMS_5.3.1_3_2013 - https://bugzilla.redhat.com/show_bug.cgi?id=986451 BZs to it should be added and committed until 09/Aug (3 weeks) - after that is started the productisation work. So an ETA to get it fixed is until 09-Aug. ============= I ran the provided unit test on the 5.3.x branch twice doing 1000+ cycles for each run but I couldn't reproduce this issue, so I am assuming the fix has been already backported. I have reproduced the same exception with BRMS.5.3.1-P4 using the unit test by Alessandro. I ran it as a stand-alone test (I did not run it as a part of Drools or BRMS test suite, I had difficulties to reproduce it when running it in the test suite, although I do not understand how this could affect the reproducability). I have created a simple Maven project containing the reproducer by Alessandro. You should be able to reproduce the problem by running 'mvn clean test' in the unzipped project.

Maven project with Alessandro's reproducer
Mario Fusco <mario.fusco> updated the status of jira DROOLS-197 to Resolved I tried Marek's test project against both the patch and 5.3.x snapshot, but I couldn't reproduce this problem. Sorry, I can actually reproduce this problem. I just didn't realize that the provide test case doesn't fail but just logs the exception stack trace. Investigating ... Verified on 5.3.1.BRMS-P04. This product has been discontinued or is no longer tracked in Red Hat Bugzilla. |
