Better Error Feedback In CollectionEntry.postFlush(PersistentCollection) ------------------------------------------------------------------------ Key: HHH-1540 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1540 Project: Hibernate Core Issue Type: Improvement Affects Versions: 3.1.2 Reporter: Daniel Gredler Assignee: Steve Ebersole Priority: Minor Fix For: 3.2.0.alpha2, 3.1.3 Original Estimate: 0.5h Remaining Estimate: 0.5h When using custom event listeners, sometimes you mess with (and initialize) lazy collections by mistake, which causes CollectionEntry.postFlush(PersistentCollection) to throw an AssertionFailure. Unfortunately, the role name of the collection is not included in the error message. I propose changing throw new AssertionFailure( "collection was not processed by flush()" ); to read throw new AssertionFailure( "collection " + collection.getRole() + " was not processed by flush()" ); or something along those lines...
