What is the base revision for the current port of JDK 7 on Mac?

[Sandeep Konchady]

Hi,

     What baseline of JDK/OpenJDK is the Mac JDK port based off of? I'd 
like to know what revisions of HotSpot, Libraries etc are used. This 
should help me understand how to set the baseline for my testing 
results. Is there a document/Wiki with this information?

Thanks,
Sandeep
