Rostislav Svoboda closed WFLY-6669.
-----------------------------------
    Resolution: Done


I checked wildfly-14.0.1.Final and it includes xercesImpl-2.12.0.SP02.jar

Decompiled xercesImpl-2.12.0.SP02.jar contains fix in DOMNormalizer as proposed in https://github.com/jboss/xerces/pull/13/files

> 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.
