Hello EG,

Two topics:

(1) There has been a flurry of mails about various proposals being
Is there a refresh of the spec planned anytime soon ? Even an informal
would be good enough for me.

(2) Could the spec leads coordinate with the lambda group so that TYPE_USE
is available as a target in the lambda branch ? At the moment it is not and
it is making life complicated for us alternating between 308 & 335 work.
my understanding this is the only change to JRE to support 308 - Is this
correct ? Are there any logistic issues in promoting this change alone to
335 branch that I am naively ignoring ?
