Drools version 6

ricardolegorret — Wed, 04 Nov 2015 01:35:09 GMT

We need to use Drools version 6 because it can handle bigger files for the number of rules.Can I use Activiti with Drools 6 instead of Drools 5?

We have a problem with Drools in a multi processor environment. We get the following error:

Invocation of init method failed; nested exception is java.lang.VerifyError: (class: ASMAccessorImpl_8411883751446576070000, method: getKnownEgressType signature: ()Ljava/lang/Class Illegal type in constant pool

After investigating a lot I found that is because de MVEL script compiler in Drools when MVEL calls the JIT compiler. The work around solution is to disable the JIT compiler in Drools, but this feature is only in Drools 6.

Se "please" is anybody has an answer to this problem?

We don't support Drools 6 yet. Please create a JIRA issue with a feature request to support Drools 6 and we can look into it.

Best regards,
