Implementing Automatic Reconnection for Netty Client
One of the first requirement of Netty ISO8588 client connector was the support for automatic reconnect.
One of the first receipts I came across was Thomas Termin’s one. He suggests adding a ChannelHandler which will schedule the calling of client’s connect() method once a Channel becomes inactive. Plus adding ChannelFutureListener which will re-create a bootstrap and re-connect if initial connection was failed.
Although this is a working solution, I had a feeling that something is not optimal. Namely, the new Bootstrap is being created on every connection attempt.
So, I created a FutureListener which should be registered once a Channel is closed.
