Agree with Steve, I think. Normalized use of "/" is assumed throughout o.h.jpa.boot.archive (see multiple methods in AbstractArchiveDescriptor). This might be limited to ExplodedArchiveDescriptor (or, at least, AbstractArchiveDescriptor subclasses). It might be best to include a #normalizeWindowsPath method on AbstractArchiveDescriptor for the descriptors to use on their ArchiveEntry#getNameWithinArchives.

However, I'd be curious to see what an OSGi container returned for BundleWiring#listResources on Windows. I assumed "/" there as well.
