[rules-users] Drools upgrade from 5.1.0 to 5.5.0.Final

Hello, I am trying to upgrade our project to jdk7 and in the process, upgrading from drools 5.1.0 to drools 5.5.0.Final and I have a few questions. 1. Is 5.5.0.Final compatible with jdk7 and is it the production version? 2. When I compile our code with 5.5.0.Final, I see the following compilation error /drools/util/DroolsRuleHandler.java:[58,25] setClassLoader(java.lang.ClassLoader...) has private access in org.drools.compiler.PackageBuilderConfiguration DroolsRuleHandler.java has this piece of code PackageBuilderConfiguration builderCfg = new PackageBuilderConfiguration(); builderCfg.setClassLoader( this.getClass().getClassLoader() ); In the new version of drools, this setClassLoader is private whereas in 5.1.0 this used to be public. Is there a way to get around this error? I would be most grateful if you could point me in the right direction. I have looked at the archives since 2011 and could not find anything in there. Is there a drools migration page somewhere that I missed? Thanks a lot for your help.
