RFR 8009581: Xpathexception does not honor initcause()

[huizhe wang]

Hi Aleksej,

Please note that in jdk8 repo, we've added jdk/test/javax/xml/jaxp to 
hold all new tests for jaxp.  All of the existing tests will be migrated 
to this place in the future.  In your case, the new test can be created 
under a new folder jdk/test/javax/xml/jaxp/XPath/8009579. Daniel's 
change request 8008738 will also add that in JDK7 repo., so please 
coordinate with Daniel when your patch is ready for JDK7.

I noticed that you're using the 'backport' bug id for this review. 
According to the process, all commits shall use the main ID.

Thanks,
Joe
