I agree: - I made this the default. The `MANIFEST_MERGE_ENABLED_DEFAULT` property already differs from Java and the docs which reassures me. I did still add a short comment beside `OBJECT_STORE_ENABLED_DEFAULT` to indicate that it differs. - I renamed `DefaultLocationProvider` to `SimpleLocationProvider` because it's no longer the default -- This is an automated message from the Apache Git Service.
