A DESCRIPTION OF THE PROBLEM :
The default implementation of javax.xml.stream.XMLEventReader produces a StartDocument event that always indicates that the "standalone" attribute was set in the original document.

The root cause of this is that the com.sun.xml.internal.stream.events.XMLEventAllocatorImpl always set the "standalone" attribute, rather than asking streamReader.standaloneSet() before setting the property of the StartDocumentEvent being created.
