*The jsr292 specification which was published for public review does not
propose any changes to the Java Language Specification.*

You said on April 18 that "Changes to the JSR 292 specification to clarify
[sic] the Java language changes that support MethodHandle are in process".
 That process appears not to have occurred, as there are no further public
drafts of the jsr292 specification.

The jsr336 specification doesn't propose any changes to the Java Language
Specification either, other than pointing to other jsrs.

jsr901, the language "maintenance" jsr, does specify language changes, but
it has no independent approval process.  The public review period for its
changes coincided with an outage in Oracle's public website for viewing the
issues it is alleged to address, which made impossible any practical review
of the changes. In any case, jsr901 contains no jsr292-related changes such
as polymorphic method signatures.

Of course, with no public access to the expert group discussions it is very
hard for me to know precisely what it was that was decided in either case.
 But based on the documents that have been published, jsr336 didn't appear
to approve for inclusion into SE 7 any language changes that relate to
