Doc Type: Bug Fix
Doc Text:
Cause: A class loader is created and cached for each class/interface loaded by the Hibernate scanner while inspecting a deployment archive containing a persistence unit. Consequence: For large archives (containing many classes/interfaces), an exception may occur: java.lang.OutOfMemoryError: Metaspace Fix: A single loader will be used by the Hibernate deployment scanner, per-persistence unit Result: Reduced memory footprint (for metaspace)
