RFR [11] (JAXP): 6857903: SAXException.initCause() does not correctly set Exception

[Jason Mehrens]

Aleksei,

You have to override all of the constructors to always disable initCause.  Actually a similar issue was covered in:

http://mail.openjdk.java.net/pipermail/core-libs-dev/2013-May/016908.html
http://mail.openjdk.java.net/pipermail/core-libs-dev/2013-June/017594.html 

Pretty much everything was hashed out in those threads.

Here is the final webrev for that:

http://cr.openjdk.java.net/~dmeetry/8009581/webrev.5/jaxp/src/javax/xml/xpath/XPathException.java.udiff.html

That should be a good cookbook for changes and tests required for this issue.  Note that it gets rid of the Exception field and maintains serial compatibility.  
Looking back on that change, I would have changed it so the InvalidClassException added the double cause as suppressed exceptions.

Hello,

Please, help to review the fix for jaxp bug that fixes SAXException to
correctly set exception cause with 'setCause' method:
http://cr.openjdk.java.net/~aefimov/6857903/dev/00/
I've tried to keep the fix miminal with respect to serial form of this
API class, i.e. kept private 'exception' field.

The new test case was added to IssueTracker56Test unit test. Testing
showed no related JCK/JTREG failures.

With Best Regards,
Aleksei
