Description of problem:

Since this issue was reported by a customer, I have created bugzilla which covers this JIRA
https://issues.jboss.org/browse/DROOLS-1013.

When the implementation of the Comparable interface is not directly declared by a Class, but the Class implements another interface that transitively extends Comparable the jitting of a constraint doing a compareTo on that class fails with the following exception:

Version-Release number of selected component (if applicable):

BRMS 6.2.0
How reproducible:

always
Steps to Reproduce:
1. Run the reproducer
2.
3.

Actual results:

Reproducer fails with methodnotfound error
Expected results:
Reproducer does not fail

Comment 1 Anton Giertli 2015-12-22 09:50:05 UTC 
This is not the same issue as reported in here
https://bugzilla.redhat.com/show_bug.cgi?id=1233976

the reproducer attached in here, fails when using 6.2.0

There is one workaround available - disable jitting.
System.setProperty("drools.jittingThreshold", "-1");


This workaround is only applicable on 6.2.0 and not for previous versions.
