            Priority: Critical


We are using docx4j 2.8.1 to generate PDFs which depends on xalan 2.7.1. When deploying our
proj to GF, after a period of time(it worked well when just starting GF), xalan threw a NPE
looks like

Caused by: java.lang.NullPointerException
	at org.apache.xml.serializer.OutputPropertiesFactory.getDefaultMethodProperties(OutputPropertiesFactory.java:260)
	at org.apache.xalan.templates.OutputProperties.<init>(OutputProperties.java:83)
	at org.apache.xalan.transformer.TransformerIdentityImpl.<init>(TransformerIdentityImpl.java:88)
	at org.apache.xalan.processor.TransformerFactoryImpl.newTransformer(TransformerFactoryImpl.java:823)
	at com.sun.xml.bind.v2.runtime.JAXBContextImpl.createTransformer(JAXBContextImpl.java:728)
	at com.sun.xml.bind.v2.runtime.XMLSe|#]

When digging into the source code Ln.260 of OutputPropertiesFactory.java, NPE is impossible
here to my opinion:

...
synchronized (m_synch_object)
...
