Motivation: Not all SSLEngine implementations permit beginHandshake being called while a handshake is in progress during the initial handshake. We should ensure we only go through the initial handshake code once to prevent unexpected exceptions from being thrown. Modifications: - Only call beginHandshake if there is not currently a handshake in progress Result: SslHandler's handshake method is compatible with OpenSSLEngineImpl in Android 5.0+ and 6.0+. Fixes netty#4718

@Scottmitch thank you very much! I had a commented it at #4718. It works well now with Android 5.0, 5.1, and 6.0 on emulator and on a Nexus 5 with the latest Android from Google. I use it on Linux desktop with OpenJDK 7 for a week without notable issues. |
