Description

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:

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