That's a good suggestion, thanks! I'm adding an additional `!context.isNegotiated` check. `isNegotiated` should be always true after the handshake. The `handshakeContext` after handling a `key_update` message would be of `PostHandshakeContext` type, we can also check for that but it seems redundant. ------------- PR Review Comment: https://git.openjdk.org/jdk/pull/21043#discussion_r1765694925
