Mark Langford updated DROOLS-1631:
----------------------------------
Description:
We are currently converting our iLog rule engine solution to a Drools based system with good success. The project is a Maven project using Spring Boot 1.5.2 and Java 1.8. We have converted 1800+ rules (including 83 decision tables) from their iLog format to Drools format. We were using version 6.2.0. The newKieSession method took approx 2 minutes on the first run to compile our rules and provide the kieSession: -
KieContainer kieContainer = KieServices.Factory.get().newKieClasspathContainer();
KieSession kSession = kieContainer.newKieSession("ric-rules");
I decided to upgrade to version 6.5.0 by updating our pom.xml.
When I ran the code again, the above newKieSession method took 20 minutes to complete. It also seems like our rule processing stalled or hung with no Exceptions being reported.
I have the following dependencies in our pom.xml
