Svetoslav Neykov created KARAF-4720:
---------------------------------------
Summary: NamespaceHandler implementations hijack namespaces
Key: KARAF-4720
URL: https://issues.apache.org/jira/browse/KARAF-4720
Project: Karaf
Issue Type: Bug
Affects Versions: 4.0.6
Reporter: Svetoslav Neykov
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:
