The JDK SunJSSE implementation now supports the TLS FFDHE mechanisms defined in RFC 7919. If a server cannot process the `supported_groups` TLS extension or the named groups in the extension, applications can either customize the supported group names with `jdk.tls.namedGroups`, or turn off the FFDHE mechanisms by setting the System Property `jsse.enableFFDHE` to `false`.
