java.rmi.ConnectException: Connection refused to host

[reikjarloekl]

ScenicView launches and can find and apparently connect to the running JavaFx-application:

Platform running

However in the console of the JavaFx-application these exceptions start repeating:

I tried setting -Djava.rmi.server.hostname=localhost on both ends (ScenicView and also the JavaFx-Application) but without any success so far.

I have no clue that the IP address is. It is none that is used by any of the interfaces on my machine. I am not even attached to a network where the IP would fit the netmask.

what exactly is attempting to be hosted here? would make it helpful to debug

I've seen this too when moved the application being inspected up to Java 17.... When I moved it back to Java 11 scenicView worked as expected. This was scenicView 11.0.2
