[PATCH]: javac[8,9] with jdk7

Although this change does make javac9 run on JDK7, that's not what's
important about it.  The changes that Liam is making here will be important
for running every future N on every future N-1.  Basically, javacN should
*never* depend on SourceVersion.RELEASE_N.

This happens (coincidentally) to allow javac9 to run on JDK7, but that's
not something that is necessarily a feature requirement.
