FULL PRODUCT VERSION :
java version "1.6.0"
Java(TM) SE Runtime Environment (build 1.6.0-b105)

A DESCRIPTION OF THE PROBLEM :
XMLStreamReader close the underlying stream when next method is called and the node type is "End Document".

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Read more than one XML from the same stream. (See source code)




EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
XMLStreamReader never close the underlying stream as says the documentation.
ACTUAL -
XMLStreamReader close the stream

ERROR MESSAGES/STACK TRACES THAT OCCUR :
Exception in thread "main" java.io.IOException: Stream closed
	at java.util.zip.ZipInputStream.ensureOpen(ZipInputStream.java:44)
	at java.util.zip.ZipInputStream.closeEntry(ZipInputStream.java:91)
	at XMLStreamReaderBug.main(XMLStreamReaderBug.java:47)

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
Overload  Stream  close method:
FileInputStream fis = new FileInputStream(FILENAME);
ZipInputStream zis = new ZipInputStream(fis){
	public void close() throws IOException {
	//Do nothing
	}
};
		
//Do something
		
fis.close();
