The stack underflowing is fixed.

In two cases, the AsyncSAXParser thread will not teminate.
1) There is an exception occures in the SAXXMLStreamReaderImpl
2) The user doesn't parse the document to the end
To make sure the AsyncSAXParser thread terminates correctly, following
modifications are done.
1) When an exception occurs in the next() method the AsyncSAXParser thread is
interrupted, because after that no call to the StreamReader is valid.
2) When an exception occures in other methods of StreamReader, a call to
StreamReader may still be valid, so the AsyncSAXParser thread shouldn't be
interrupted in this case.
3) In the close() method, if the AsyncSAXParser thread is still alive,
interrupt it.
But if the user doesn't close the StreamReader after using it, the
AsyncSAXParser thread may never terminate. So user should call the close()
method.
>In the fix that you made in SAXXMLStreamReader.initialElementAttrs() you
>added a check for duplicate attributes that I didn't understand. A SAX
>parser already does this well-formedness check. Is there a reason for
>doing that again in the XMLStreamReader?
The SAX parser cann't recognize the element such as "<root xmlns:a='xxx' xmlns
:b='xxx' a:attr='1' b:attr='2' />", so I check it myself.

> The initialElementAttrs() method of SAXXMLStreamReader sets the prefix of
attributes to null if it finds no colon in the attribute name; the problem with
this is that getAttributeNamespace() uses this prefix when looking up the
namespace uri with a call to getNamespaceURI on the NamespaceContextImpl, and
this method throws an IllegalArgumentException if null is passed in.
