Trait Hierarchy is not rebuilt correctly when merging packages
Fixed by https://github.com/sotty/drools/commit/d8d6196fa4b5a6f747ae8f730d1f57eb668b7f5a
Mario Fusco <mario.fusco> updated the status of jira DROOLS-393 to Resolved
This is part of a forward port of fixes applied to the 5.6.x community version and 6.1.x version. We would like to have the acks set to cherry pick into 6.0.1.
Verified that the fix is present in BRMS 6.0.1 ER2 and relevant tests pass.
