jtreg testing integrated

jtreg is now open source, as of just before JavaOne. See http://openjdk.java.net/jtreg

There is a small new utility called "jtdiff" that comes with jtreg  
that may do what
you want.  It will do n-way comparison of any JavaTest-type results  
(meaning jtreg, JCK, etc)
where each set of results can be given as a JavaTest work directory,  
report directory,
or just the summary.txt file within a report directory. The output can  
be plain text or HTML.

jtdiff is within jtreg.jar, so the easiest way to invoke it is
	java -cp jtreg.jar com.sun.javatest.diff.Main <args>
