Subject: [PATCH] Refine
 DefaultPersistenceUnitManager#determineDefaultPersistenceUnitRootUrl

This commit refines the implementation to be more
lenient when defaultPersistenceUnitRootLocation is equals
to ORIGINAL_DEFAULT_PERSISTENCE_UNIT_ROOT_LOCATION and an
IOException is thrown, which happens when running on
native image.

Closes gh-29137
