What is the difference in using this

@OverRide
public void exceptionCaught(ChannelHandlerContext ctx, Throwable cause) throws Exception {
Channel ch = ctx.channel();
NettyChannel channel = NettyChannel.getOrAddChannel(ch, url, handler);
try {
handler.caught(channel, cause);
} finally {
NettyChannel.removeChannelIfDisconnected(ch);
}

and using this (I found it while walking through netty )

@OverRide
public void exceptionCaught(ChannelHandlerContext ctx,Throwable cause) {
cause.printStackTrace();
ctx.close();
}
