I wrote to Tim in a separate email and suggested that it would be 
helpful to do a PIT testing no matter which milestone we go into. Sorry 
I didn't Cc you and the alias. The QA team had agreed to help us perform 
PIT testing for JDK integration including 6 and 7. They've already done 
it a couple times for JDK6.

Tim,

Please send the link to a JPRT build when you have it. Thanks.
