BUG: SAXParser endElement reports incorrect local name w/ namespa ces

["Sieger, Nicholas" <ns...@netperceptions.com>]

I found a problem with the 1.1.* versions of the SAXParser where
the following example XML would not fire correct endElement events - the
local names reported still had the namespace prefixes attached for
elements a and b.  This same test run with version 1.0.4 works correctly.
Source code reproducing the problem follows.

<?xml version="1.0" standalone="yes"?>
<test:a xmlns:test="/dev/null">
 <test:b>
  <test:c></test:c>
 </test:b> <!-- endElement reports the local name to be "test:b" -->
</test:a>  <!-- endElement reports the local name to be "test:a" -->

This XML fires events properly, including reporting the correct
namespaces:

<?xml version="1.0" standalone="yes"?>
<a xmlns="/dev/null">
 <b>
  <c></c>
 </b>
</a>

Can anyone verify this as a bug, or is the test malformed?
