We plan to pass all of Oracle's test suites on currently supported platforms
before integrating into jdk7u.  What subset of those test suites the OSX 
port
must pass before integration into jdk7u is an open question right now.  Imo,
at least the jdk7 jcks.

A major goal of having a separate 7u-derived osx port development forest 
is to
avoid pushing potentially destabilizing changes directly into 7u.
