>
> in 4.1.43 netty made a change to their SslHandler to always use heap buffers
> for JDK SSLEngine implementations, to avoid an additional memory copy.
> However, our {{NettyBufferPool}} forbids heap buffer allocations.
> We will either have to allow heap buffer allocations, or create a custom
> SslHandler implementation that does not use heap buffers (although this seems
> ill-adviced?).
