NullPointerException on jnlp file execution on java 9

Question

I am getting the exception below (endlessly) after run my jnlp app. I am using the java 9 early-access release. It was working on java-8 so I thought it is about the changes on 9. I could not find anything in java-9 issues. Any idea about the reason?

Exception in thread "JavaFX Application Thread" java.lang.NullPointerException

Edit: It is working on java-8 perfectly. So problem should be about java-9 changes.

Try running with debug: https://stackoverflow.com/questions/686061/how-can-i-debug-applications-under-java-web-start-jnlp — jrtapsell, Sep 06 '17 at 13:09
What code did you try? and the stack trace seems incomplete if it does not point to the line of your code that causes the exception. — Naman, Sep 06 '17 at 18:23
@AlanBateman it is a very big app so very hard to understand the reason. There is no link to our code in stack trace. I will try to find the exact problem. — rdonuk, Sep 07 '17 at 07:42
