[rules-users] KieBuilder.buildAll() causing exception

Hi Guys, I'm a pretty recent Drools user. I'm trying to update a project to stop using the deprecated KnowledgeBase. I've followed examples on http://blog.athico.com/2013/10/configuration-and-convention-based.html <http://blog.athico.com/2013/10/configuration-and-convention-based.html> , but an exception is being thrown when trying to build the KieBases. Drools version:6.0.0.Final Java version: 1.7.0_45 Code snippet: ... final KieServices ks = KieServices.Factory.get(); final KieRepository kr = ks.getRepository(); final KieFileSystem kfs = ks.newKieFileSystem(); //ruleScript is simply a string containing the rules kfs.write("src/main/resources/com/company/test/rules/rules.drl", ruleScript); KieBuilder kb = ks.newKieBuilder(kfs); kb.buildAll(); if (kb.getResults().hasMessages(Level.ERROR)){ configuration.getLog().error("\nSomething wrong here!\n\n"); } final KieContainer kContainer = ks.newKieContainer(kr.getDefaultReleaseId()); session = kContainer.newKieSession(); ... The following exception is thrown: java.lang.instrument.IllegalClassFormatException: Error while instrumenting class org/drools/compiler/lang/DRL6Lexer. at
