Description

In jaxp-ri-1.4.4, com.sun.org.apache.xerces.internal.impl.dv.DTDDVFactory.getInstance() is synchronized, this could cause performance issue when a lot of thread access this method at the same time.
Per the post[1], this issue already get resolved after xerces-2.9.1, we need ship latest xerces but not the buggy jaxp-ri.
