[rules-users] KnowledgeAgent custom class loader not working for PKG resources

[Esteban Aliverti]

Could you please try using 5.4.0-SNAPSHOT? I tried to reproduce your error
in that version, but I couldn't. Using 5.3.1 I experienced the error you
mentioned.
Please note that in order to change drools version you need to have a
binary .pkg compiled using the same version.

Best Regards,
