public class FactorialServerHandler
extends io.netty.channel.ChannelInboundMessageHandlerAdapter<BigInteger>

Handler for a server-side channel. This handler maintains stateful information which is specific to a certain channel using member variables. Therefore, an instance of this handler can cover only one channel. You have to create a new handler instance whenever you create a new channel and insert this handler to avoid a race condition.
