[KARAF-4720] Prevent NamespaceHandler implementations from hijacking
namespaces
NamespaceHandler implementations in Karaf will return a schema location
from getSchemaLocation even for namespaces they don't own, essentially
replacing the xsd that corresponds to the requested namespace. That leads to
errors that make no sense and inability to use the bundles that implement the
handlers.
Triggered by https://issues.apache.org/jira/browse/ARIES-1503 and
https://github.com/apache/aries/commit/9a1ff22cbd29006d24a42e3e1274dfa493501ed9
in particular.
The error I was seeing when trying to use the JAAS module:
```
