----------------------------------------
Hi Gary, I'm trying to answer that question for you, but so far I've been
unable to figure out how to run the test suite. I originally downloaded a
source distribution to make my modifications, but that doesn't appear to have
the tests included in it. I then tried cloning the Git repo and checking out
the SVN repo and neither of those seem to include the tests either. Any clue
how I can get my hands on the tests? FWIW, here's the error I'm getting when I
run "ant smoketest" or "minitest":
tests-not-available:
[echo] [tests] The tests do not seem to be present in ../test
[echo] [tests] You must have checked out from CVS to run the tests,
[echo] [tests] it is not included in binary distributions.
[echo] [tests] See http://xml.apache.org/xalan-j/test/ for more info.

> Key: XALANJ-2419
> URL: https://issues.apache.org/jira/browse/XALANJ-2419
> Project: XalanJ2
> Issue Type: Bug
> Components: Serialization
> Affects Versions: 2.7.1
> Reporter: Henri Sivonen
> Attachments: XALANJ-2419-fix.txt, XALANJ-2419-tests.txt
>
>
> org.apache.xml.serializer.ToStream contains the following code:
> else if (m_encodingInfo.isInEncoding(ch)) {
> // If the character is in the encoding, and
> // not in the normal ASCII range, we also
> // just leave it get added on to the clean characters
>
> }
> else {
> // This is a fallback plan, we should never get here
> // but if the character wasn't previously handled
> // (i.e. isn't in the encoding, etc.) then what
> // should we do? We choose to write out an entity
> writeOutCleanChars(chars, i, lastDirtyCharProcessed);
> writer.write("&#");
> writer.write(Integer.toString(ch));
> writer.write(';');
> lastDirtyCharProcessed = i;
> }
> This leads to the wrong (latter) if branch running for surrogates, because
> isInEncoding() for UTF-8 returns false for surrogates. It is always wrong
> (regardless of encoding) to escape a surrogate as an NCR.
> The practical effect of this bug is that any document with astral characters
> in it ends up in an ill-formed serialization and does not parse back using an
> XML parser.
