Several JLS changes was proposed. One for invoking method handles,
one for specifying constant method handle and an other for
invokedynamic. The changes for invokedynamic and constant method handle
was delayed due to its interaction with lambda.
You're right that these changes was first submitted to coin,
but it was latter decided that the only the syntax change implemented
in Java 7, invoking a method handle, will be done under JSR 292.

I don't understand exactly what you mean.
Coud you be a little more specific ?
