Added test case JPAUnitTestCase.
When using the "searched" selectCase (without argument), then everything is fine.
When using the simple "valued" selectCase (with one argument), then the custom type (in this case for enum) is not found.

I would expect that the expected type from the argument to selectCase (here: contactRoot.get("type")) should be re-used for the condition (ContactTypeEnum.INDIVIDU).
