Environment

Resolution

The workaround for this issue is to manually set the SAXParserFactory used by the JVM when starting the process:

--J=-Djavax.xml.parsers.SAXParserFactory=com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl

Optionally, if you don't need to use external parsers libraries (like Xerces), please remove them from the classpath.
