Major Description
This might be a problem only on equinox... if felix is ignoring some spec bits.
When we scan an embedded zip file in a bundle, we just do a string match on the suffix to the entry path. But for plain bundle entries, we use the bundle.findEntries which only matches the last path component. So, for instance, if you look for META-INF/persistence.xml you'll find it in an embedded jar file but not in WEB-INF/classes/META-INF/persistence.xml.
