until now I could start the jar files created by b4j multiple times simultaneously. for some reason, I can do it only once now. if I start the jar file again after it is already open the last one closes automatically. is this something new in b4j?
ok, it's because of the UDPSocket. i tried to run it on the same port and it is not possible.
so now i wonder how UDPSocket actually works.
let say i have 2 clients that i want to connect to each other and send UDP Packets between them but i guess it is better to start a new thread about this question
