DTD validation errors leave XML file locked

           Summary: DTD validation errors leave XML file locked
           Product: Xerces2-J
           Version: 2.3.0
          Platform: PC
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Major
          Priority: Other
         Component: SAX
        AssignedTo: xerces-j-dev@xml.apache.org
        ReportedBy: javacrypto@yahoo.com


If an error occurs with when validating a DTD, parsing stops, but the XML file 
that was being read remains open and locked, so it cannot be edited or moved.

To reproduce this, open the XML file with a text editor, and point the DTD to a 
file you know does not exist. When I do this, my error handler correctly 
reports the missing DTD, but the file remains locked until the VM exits. In my 
case, the VM is a web server, so I cannot fix or move the file until the web 
server restarts.

I tried to fix the problem by re-throwing the exception in the error handler, 
but this had no effect.

A possible work-around for this would be to launch the parsing in a separate 
VM, but that sounds messy and unnecessary. It would be better to close the file 
in a finally block or something.

This happened in older versions of Xerces too. See bug #8053 for Xerces-J:

This probably happens on other platforms besides Win2K, but I can't test them.
