Release Note: RC2 and ARCFOUR Algorithms Added to jdk.security.legacyAlgorithms Security Property

The RC2 and ARCFOUR (RC4) algorithms have been added to the "jdk.security.legacyAlgorithms" security property in the `java.security` configuration file. The `keytool` tool issues warnings when a weak RC2 or ARCFOUR algorithm is used for its commands associated with secret key entries in the keystore.
