DefaultPersistenceUnitManager may configure a persistence unit root URL that does not point to a file or directory [SPR-14749] #19315

Andy Wilkinson opened SPR-14749 and commented

When using a custom class loader, a call to getResource("") may return a URL that points inside a JAR. This may become the case in Spring Boot, for example. This adversely affects DefaultPersistenceUnitManager.determineDefaultPersistenceUnitRootUrl() which returns a URL that Hibernate then logs a warning about.

It looks like the same ResourceUtils.isJarURL(url) and ResourceUtils.extractJarFileURL(url) arrangement that is in buildDefaultPersistenceUnitInfo may also be appropriate in determineDefaultPersistenceUnitRootUrl().

Affects: 4.3.3

Good point: We're explicitly extracting the jar file URL there now (if we happen to receive a jar entry).
