How to cancel recvTaggedNonBlocking or how to handle disconnect in java binding?

[lucyge2022]

Hi, I planned to exchange tag info after client and server establish connection, and server will use recvTaggedNonBlocking on server side to receive metadata infos from client, so if there's a disconnection, how do I cancel recvTaggedNonBlocking from its request? or is there a way to cancel the resulting UcpReqeust? Or simply close the disconnection UcpEndpoint will just be enough? Thanks!
