Description Tomas Hoger 2021-10-19 18:35:13 UTC 
It was discovered that the default TLS cipher suite configuration in the JSSE component of OpenJDK preferred certain weak ciphers over stronger ciphers.  This issue was addressed by:

- Preferring ciphers with forward secrecy.
- Lowering priority of ciphers using RSA encryption key exchange.
- Lowering priority of ciphers using SHA-1 hashing algorithm.

Comment 1 Tomas Hoger 2021-10-19 20:15:34 UTC 
Related noted in the Oracle JDK release notes:

"""
security-libs/javax.net.ssl
➜ Updated the Default Enabled Cipher Suites Preference

The default priority order of the cipher suites for TLS 1.0 to TLS 1.3 has been adjusted.

For TLS 1.3, TLS_AES_256_GCM_SHA384 is now preferred over TLS_AES_128_GCM_SHA256.

For TLS 1.0 to TLS 1.2, some of the intermediate suites have been lowered in priority as follows:

Cipher suites that do not preserve forward secrecy have been moved lower in priority than those that do support forward secrecy.
Cipher suites that use SHA-1 have been moved lower in priority.

See JDK-8163326 (https://bugs.openjdk.java.net/browse/JDK-8163326)
