Motivation: We should aim to always use heap buffers when using the JDK SSLEngine for now as it wants to operate on byte[] and so will do internal memory copies if a non heap buffer is used. Beside this it will always return BUFFER_OVERFLOW when a smaller buffer then 16kb is used when calling wrap(...) (even if a very small amount of bytes should be encrypted). This can lead to excercive direct memory usage and pressure for no good reason. Modifications: Refactor internals of SslHandler to ensure we use heap buffers for the JDK SSLEngine impelementation Result: Less direct memory usage when JDK SSLEngine implementation is used |
