[rules-users] class loading problems with 5.3.0-Final and 5.4.0-SNAPSHOT

[Mauricio Salatino]

Hi guys,
I'm working here trying to find out a little problem that I'm having with
Drools 5.4.0-SNAPSHOT and 5.3.0-Final.
I'm using WSO2 container to deploy a very simple service and when a rule
gets activated the following exception appears (with 5.4.0-SNAPSHOT):

Exception in thread "Thread-44" java.lang.ClassCircularityError:

I'm worried to see that I don't have any problems with 5.1.1 but with later
version all throw similar issues.
I will be trying to solve this issue, but if someone has a clue about what
can be happening here, please let me know.

I know that this can be a particular issue with WSO2, but it looks like
something has changed inside drools.

Cheers
