Hi everybody,
after some discussion with Christian and Andrea about current security
modules configuration limits in the ability to backport them, I was
thinking if we could try to introduce some flexibility to allow backporting
in simple cases.
Talking with Andrea we found that 1.4.5 version of XStream allows ignoring
unknown attributes (so that the unmarshalling doesn't break loading a newer
configuration with unrecognized properties): you can find some reference
here: http://jira.codehaus.org/browse/XSTR-691.
Moreover, we could introduce a metadata map, similar to the one used in
Catalog objects, to be used in backported versions.
So, what we could do is:
- upgrade XStream to 1.4.5 (from the current 1.4.3) and enable the
unrecognized attributes ignore flag
- introduce the metadata map in security configurations
Any opinions on this?
Regards,
Mauro Bartolomeoli
