@errantepiphany The leading PR (kiegroup/droolsjbpm-integration#1739) has been merged into the master. So it is ready to merge this following PR so that it can be cherry-picked into 7.3.1. BTW, rebased from master, should be no conflict.

@rhtevan Perhaps change one of the tests by setting the env var to true? I ask because false is the default, so testing for false doesn't test that a different env var value was picked up. After that, I will merge the PR, however then we'll need another PR for the 7.3.x branch (with the cherry-picked commit in it). That PR will be labeled "on hold" until after the 7.3.x branch gets tagged as 7.3.0.GA, at which point we can merge PRs that are intended for 7.3.1.

@errantepiphany Good point. Moved away from using the default value in tests. And as per your suggestion, created another PR against 7.3.x branch. But for some reason, not able to set the 'on hold' label for that PR
