Hi all,

Can I have a reviews for the following change:

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.
