>            Priority: Major

> It seems the debugger app wants to integrate nicely into macOS and uses some 
> private API for this. This worked fine with all Java versions including 8, 
> but does no longer work with 9.
> Java 9 provides new APIs for this, but till PDFBox can depend on Java 9 (or 
> the next LTS Java 11) it should at least catch this and not crash....
> The application does not start, and instead displays a dialog with a stack 
> trace.
> Console Output + StackTrace:
> {code}
> WARNING: An illegal reflective access operation has occurred

> To workaround this problem I have to run the debugger app using JDK 8. This 
> is ok for now, but very annoying.
