➜ Increase the priorities of GCM cipher suites
In TLS, a ciphersuite defines a specific set of cryptography algorithms used in a TLS connection. JSSE maintains a prioritized list of ciphersuites. In this update, GCM-based cipher suites are configured as the most preferable default cipher suites in the SunJSSE provider.
In the SunJSSE provider, the following ciphersuites are now the most preferred by default:
TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384
