Release Note: The Default TLS Diffie-Hellman Group Size Has Been Increased from 1024-bit to 2048-bit

The JDK implementation of TLS 1.2 now uses a default Diffie Hellman keysize of 2048 bits when a TLS_DHE cipher suite is negotiated.

As a workaround, users can revert to the previous size by setting the `jdk.tls.ephemeralDHKeySize` system property to 1024 (at their own risk).
