Comment 2 Marek Winkler 2016-04-14 13:02:38 UTC 
The freeze does not occur on 6.3.x branch (please note that test method withResultTest fails - not sure if this would be expected?).

The freeze occurs on 6.4.x and master branches.

thread dump of the hanging still occuring on latest snapshot.

Hi, I'm experiencing this bug again, or it might be a different bug. The repro steps are similar. I call getQueryResults on the RHS of a rule, and the rule hangs. I attached a zip with a repro, and Thread dump. I'd make a new bug in bugzilla, but I can't seem to make new bugs in BRMS 6.
Comment 10 Marek Winkler 2016-07-18 07:23:27 UTC 
Xin Guo, 

thanks for reporting the problem. The reason why you could not create a new Bug in Bugzilla is that we moved to JIRA [1]. Please create a new issue there. 

Thanks again!
