We build internally with a JDK6 version as the bootstrap version, so I 
would expect that any issue that pops up with building 7 using 6 would 
be fixed quickly.

That said, I *think*, but I'm not sure, that we're using 6u14 right now 
as the bootstrap JDK6.  And, that's almost 2 years old at this point, so 
can't see any issue with using any reasonably recent JDK6 or OpenJDK6 
build as the bootstrap.
