Re: [rules-users] 5.3.0.Final throws RuntimeDroolsException: Unable to merge resource attribute for type declaration

Edson, Thanks for your feedback. I've have created an eclipse/maven project to duplicate this problem but I couldn't figure out how to open an issue in Jira (perhaps I don't have permission). If I include all the dependent libraries in a zip file (for convenience) the zip will be 7MB (which might not be so convenient after all). Please let me know how I can open a new issue in Jira and/or how best to deliver this project to you.

Can any of you please open a JIRA with a small test case and/or instructions on how to reproduce plz?

In Drools 5.2.0 there was no problem adding this KnowledgePackage multiple times but apparently 5.3.0 doesn't cope with it well. I'm still not sure if that is a feature or a defect in 5.3.0. In any event doing the following make the exception go away. I'm still curious if this is a feature or a defect in 5.3.0. Any thoughts or opinions regarding are welcome.
