        Description

        If javac encounters a native method with no arguments in either MethodHandle or VarHandle, an NPE will occur:

        //Test.java
        package java.lang.invoke;

        class MethodHandle {
           native Object m();
        }

        javac -source 8 Test.java

        warning: [options] bootstrap class path not set in conjunction with -source 1.8
        1 warning
        An exception has occurred in the compiler (9-internal). Please file a bug against the Java compiler via the Java bug reporting page (http://bugreport.java.com) after checking the Bug Database (http://bugs.java.com) for duplicates. Include your program and the following diagnostic in your report. Thank you.
