Alan, David and other team!
Resending the previous RFR 8009581 v.1. It might lost among the pack posts.
Best regards,

Hello Alan, David and other experts,
I presents the second version of fix for XPathException class for your
review: http://cr.openjdk.java.net/~dmeetry/8009581/webrev.1/
<http://cr.openjdk.java.net/%7Edmeetry/8009581/webrev.1/>
The serialized form remains the same in this patch, as was suggested.
I have also done some tests with serialization/deserialization of
XPathException class with different JDK versions. The class serialized
on JDK with patch was successfully deserialized by JDK versions
(6,7,8) without fix and vice versa.

Alan,
The XPathException class doesn't have any fields only methods (it had a
'cause' method, but it was deleted in suggested fix).
It had a cause field that was deleted not a method, hence the change
to the serialized form that Alan is highlighting.

And, as I can see,
there is no need to control what information is saved or to append
additional information to the serialization stream.
So, I think the readObject/writeObject is not required here.

Hi all,
Can I have a reviews for the following change:
http://cr.openjdk.java.net/~dmeetry/8009581/webrev.0/
<http://cr.openjdk.java.net/%7Edmeetry/8009581/webrev.0/>
Summary:
There is an erroneous behavior in 'initCause' method of
javax.xml.xpath.XPathException class.
Lets look at the following situation:
XPathException is created with 'XPathException(String )' constructor
and then the cause is initialized with 'initCause' method. Such
initialization sequence of actions isn't restricted by XPathException
[1] and Throwable [2] docs.
After that a cause is retrieved by 'getCause()' method: this call
returns incorrect cause = 'null'. It should return the same cause as
was used in 'initCause'. And this is the erroneous behavior.
Suggested fix (with regression test) is applicable both for JDK 8
and 7.
Exceptions are serializable so I think this may require further
investigation to see if a readObject/writeObject is required.
