If we register OP_WRITE on a SocketChannel, it seems selectionKey.isWritable() method always return TRUE. Will there be any specific scenario that it returns FALSE for a socket channel?

It is true unless the socket send buffer is full, which only happens if the receiver's receive buffer is full. – user207421 Apr 24 '19 at 09:47
