This is a bug [1] that was fixed in Xerces-J back in 2007. However, you are using Sun's implementation, not Apache Xerces-J. We cannot do anything about the problem you're having with this implementation as we have no influence over its codebase. You need to pursue this with the JDK vendor if you want a fix there.
