[rules-users] 7x slower .DRL compilation after switching 5.1.1 to 5.2.0

Hi, while we used on Drools 5.1.1 our rules compiled in approx 1 min, after switching to 5.2.0 the compilation time increased to approx 7 mins. Our compilation is performed programmatically via KnowledgeBuilder by the user application itself. What we are possibly doing wrong? Just to mention that after the switch our .DRL code that compiled successfully under 5.1.1 needed much fixing, because it completely broke under the 5.2.0 (more strict type casting, "||" became "or", access to static Java methods and fields requires now explicit class imports instead of the package imports as before, etc.). I searched but didn't find any "migration guide". Is something like that available?
