webstart + jdic problem

Witam
problem mam następujący:
aplikacja napisana w javafx + java wykorzystuję bibliotecę jdic, aby można było otworzyć pliki znajdujące się na komputerze. Używam funkcji Desktop.open(File);
Program działa poprawnie jeśli kompiluję go jako dekstop application
jedna jako webstart pojawiają się wyjątki:
