Tyrus client does not need to have an appserver! :)

Please see Tyrus documentation and blogpost Reducing WebSocket client jar size with ProGuard (you can get down to 500 kB with JDK 7+).

About the size - it can be minimized even more, but with some refactoring in Tyrus code. The comparison of WebSocket and plain socket is not very accurate - plain socket does not need to implement HTTP and (traditionally) did not have NIO support (that came with Java 7). Another part is the WebSocket protocol implementation, which is not that difficult but also its not just sending byte[] to the wire - there is some opening handshake, signalling frames and mandatory strict UTF-8 encoding/decoding.

So I guess you could find more simple API implementation, but sticking to something which is maintained and is part of Java EE does not seem bad to me - you have the possibility to choose the implementation (Tyrus is just one of them, there are others) and your client will be ready for inclusion to Java EE application if that would ever happen. (Editors note: I work on Tyrus, so my answer is most likely biased).
