> While debugging some other issues I noticed a few minor inconsistencies and
> suspected logic bugs in the netty handler changes related to netty 4:
> 1.) Classes (RequestServerHandler, ResponseClientHandler) overriding
> ChannelInboundHandlerAdapter.exceptionCaught() are still calling getCause()
> on the passed Throwable even though what's being passed in now is the actual
> cause instead of a wrapper.
> 2.) ResponseClientHandler.channelInactive() isn't calling
> ChannelHandlerContext.fireChannelInactive() like RequestServerHandler does. I
> believe this is an oversight and not by design.
> 3.) ResponseClientHandler.exceptionCaught() is gating the LOG.warn() call
> with a LOG.isDebugEnabled() check. I suspect this gate should be removed so
> the warning gets logged properly.
