Description
A new TLS extension, "Negotiated Finite Field Diffie-Hellman Ephemeral Parameters for TLS" (FFDHE extension), was proposed:

    https://datatracker.ietf.org/doc/rfc7919/

We may want to consider to support FFDHE extension so that 2048+ bits DH can be the default preferable strength from JDK 6 to JDK 9.
Comments
No API is planned. Plan to backport to previous releases.
