[rules-users] activation dependent of rule order in drl file in 5.2.0.Final?

Hi, because of https://issues.jboss.org/browse/JBRULES-2942 i just migrated our (maven) project to 5.2.0.Final - we depend on salience in some of our rules. However, after the salience issue was gone I'm facing a new problem in several test cases: Rules in previously (drools 5.1.1) working rule files don't get activated anymore when I insert facts - none at all. When moving the rule expected to fire (see "rule 4" in attached file) to the first position in the drl file then suddenly several rules get activated and the expected rule fires. This shouldn't be the case, shouldn't it? Or do I miss something obvious here? Could a corrupt file somehow cause this? I attachached the rule file which causes the problem (I needed to obfuscate some names, sry). It is quite simple. I experienced a similar issue (again since 5.2.0.Final) with rules generated from templates, where I had to change the constraints order in the templates' LHS for then generated rules to get activated at all. First I would like to know if my statement that the rule position in the drl file shouldn't influence the activation (I don't mean firing or order of activations) of a rule at all, is correct. I don't use agenda groups. And second if someone experienced similar issues. I will try to build a test case which hopefully can reproduce this as soon as possible. Florian
