public boolean isSharable()

Overrides default io.netty5.channel.ChannelHandler.isSharable.

Doc from io.netty5.channel.ChannelHandler.isSharable.

Returns true if this handler is sharable and thus can be added to more than one ChannelPipeline. By default, this method returns false. If this method returns false, you have to create a new handler instance every time you add it to a pipeline because it has unshared state such as member variables.
