Doing a quick google. The problem seems to be the jacob instrumentation, it cannot
instrument very large classes, as it makes the LOC too large. Jacob isn’t needed anyway,
and can be disabled:

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.
