Avoid calling Thread.getContextClassloader() to improve performance ------------------------------------------------------------------- Key: JBRULES-3489 URL: https://issues.jboss.org/browse/JBRULES-3489 Project: Drools Issue Type: Enhancement Security Level: Public(Everyone can see) Components: drools-compiler, drools-core Affects Versions: 5.3.1.Final, 5.4.0.CR1 Reporter: Edson Tirelli Assignee: Edson Tirelli Fix For: 5.3.2.Final, 5.4.0.Final, 5.5.0.Beta1 When a Drools instance is deployed into Gigaspaces container with the Java Security Manager enabled, accessing the context classloader is an extremely heavy operation (over 400 times slower) and also causes thread contention among different threads running different sessions. In order to work around this problem, change the code to avoid accessing the context classloader as much as possible, without compromising thread safety.
