Hi there,
using bytecode enhancement with enableDirtyTracking=true and enabled second level cache, I'm encountering lazy init exceptions when the enhanced codes tries to clear the dirty attributes:
{noformat}

The issue
This error happens in TwoPhaseLoad.doInitializeEntity, when the hydrated state of JafSid ExtendedSelfDirtinessTracker is applied during enhancement . getGroups Accessing size () is resolved.

The collection that needs to be taken from this.xrefLoadingCollectionEntries throws the LazyInitializationException.
Maybe this already gives enough clues. As the inheritance structure of the entities is quite difficult, I wasn't able to prepare an isolated test case yet, but maybe this already helps to fix uninitialized collection triggers the issue exception . |
