[jira] Created: (CXF-2625) Class-loader leakage in org.apache.cxf.jaxb.JAXBDataBinding.JAXBCONTEXT_CACHE

Class-loader leakage in org.apache.cxf.jaxb.JAXBDataBinding.JAXBCONTEXT_CACHE 
------------------------------------------------------------------------------

                 Key: CXF-2625
                 URL: https://issues.apache.org/jira/browse/CXF-2625
             Project: CXF
          Issue Type: Bug
          Components: JAXB Databinding
    Affects Versions: 2.1.5
            Reporter: Daniel Feist


See: http://old.nabble.com/Classloader-leakage-when-using-JAXB-binding-in-appServer-td26101445.html

Here is appears we have another map the maintains references to the generated classes and in turn to the webappClassloader that is no more expect this one doesn't even try to be weak.  I notice there is a clearCaches() method but i'm unsure about using that at anytime in runtime because even though i'm taking down one cxf Service there may be user services alive using jaxb at the same time. 

I don't have a patch for this one currently.

[jira] Resolved: (CXF-2625) Class-loader leakage in org.apache.cxf.jaxb.JAXBDataBinding.JAXBCONTEXT_CACHE

Posted by "Daniel Kulp (JIRA)" <ji...@apache.org>.
     [ https://issues.apache.org/jira/browse/CXF-2625?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Daniel Kulp resolved CXF-2625.
------------------------------

       Resolution: Fixed
    Fix Version/s: 2.2.6
                   2.1.9
         Assignee: Daniel Kulp


Fixed for 2.2.6 as we changed the CachedContextAndSchemas to hold onto the JAXBContext using a weak reference.   That was holding onto the Class objects which prevented it from being cleaned out.
