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.

-Alan.
