error when using native-image with netty, unable to build a native-image

[damnms]

hi, i have a little chat application, which is more or less a wrapper so i dont have to use the browser and can finetune some things, e.g. that chat has only one text field where one has to write /pm $user to write a private message. my application makes this more fancy and a javafx window pops up when a private message is recieved or send.
anyway, that application works and i'd like to package that with native-image so i can produce .exe, .dmg and for my linux workstation deployable packages. but it fails and i am really lost. i am absolutely new to graalvm, i have a bit knowledge of jlink/jpackage.

the error is this:
