hg: jdk7/tl/langtools: 6979683: inconsistent interaction of reference cast with box/unbox conversions leaves out a useful case

You appear to have added a new kind of casting conversion not yet proposed
or described in JLS3 (section 5.5).  Is there a language change proposal
that corresponds to this code change?
