RFC: Bump required Java version for JavaHL to 1.6

Subject says it all. Two reasons:

  * Java 5 has been officially dead since 2009
  * 1.9 JavaHL uses Java6 APIs

It's possible to cross-compile for Java5 using newer JDKs, but the
compiler only checks language features, not library usage; for the
latter, you actually need Java5 classes available. I've not been able to
find a J5SE download that doesn't require creating an account with Oracle.

Alternatively, I'd be happy to keep the compatibility guarantee, but
someone would have to make the Java 5 bootstrap classes available on a
buildbot and use them for the JavaHL build and tests so that we can
actually verify compatibility.
