NoSuchMethodError during rule execution when using compareTo transitively in LHS

Solution Verified - Updated -

Issue

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:

Exception in thread "Thread-0" java.lang.NoSuchMethodError: java.time.LocalDateTime.compareTo(Ljava/time/LocalDateTimeI
