org.xml.sax.helpers.AttributesImpl can enter infinite loop

           Summary: org.xml.sax.helpers.AttributesImpl can enter infinite
                    loop
           Product: Xerces2-J
           Version: 2.0.0
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Minor
          Priority: Other
         Component: SAX
        AssignedTo: xerces-j-dev@xml.apache.org
        ReportedBy: hurwood@att.net


The following code fragment enters an infinite loop.
-----
import org.xml.sax.helpers.AttributesImpl;
AttributesImpl emptyAttributes = new AttributesImpl();
AttributesImpl copyAttributes = new AttributesImpl(emptyAttributes);
copyAttributes.addAttribute("", "", "", "", "");
-----
It appears that the 'ensureCapacity' function assumes that either the 
'data' array is null, or its length is greater than zero.  Constructing
an AttributesImpl object from an empty Attributes collection sets
the 'data' array to an array of length zero.  Next time 'ensureCapacity' is
called it enters an infinite loop.

The problem can be seen in current CVS version (Revision 1.5)
