             Summary: Classloader leak trigerred by DOMNormalizer#abort in xercesImpl-2.11.0.SP4
                 Key: WFLY-6669
                 URL: https://issues.jboss.org/browse/WFLY-6669
             Project: WildFly
          Issue Type: Bug
          Components: XML Frameworks
    Affects Versions: 10.0.0.Final
            Reporter: Mathieu Lachance
            Assignee: Jason Greene
            Priority: Critical


XERCESJ-1667 is a fix that was incorporated in the SVN trunk of the apache xerces project. Though it was never ported back in JBoss/Xerces github.

In our case, the classloader leak is triggered by the OpenSAML library which depends on Xerces, but lets be honest, this could have been anything.
