Subject [jira] Updated: (CXF-3339) ClassLoader issue with cached JAXBContext by packagename
Date Tue, 15 Feb 2011 17:35:57 GMT

Joakim Olsson updated CXF-3339:
-------------------------------

    Description: 
When using the same REST-integration from two different WAR's we got a nice "JAXBException
occurred : class packagename.Classname nor any of its super class is known to this context"
from one of the applications.

I tracked this to the AbstractJAXBProvider and the packageContexts being keyed on the string-representation
of the package.

The following naive patch (towards the 2.3.x-fixes branch) solved the problem for us. There
probably is a better solution.
