Also, note that before <https://issues.apache.org/jira/browse/GROOVY-10153>
was fixed, the compiler rejected the program with the following error message:

    
    
    org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
    Main.groovy: 2: The type ? is not a valid substitute for the bounded parameter <D extends M>
     @ line 2, column 31.
         static Foo<Bar<Byte, Byte>, ? super Bar<Byte, Byte>> foo = new Foo<>(new Bar<>())
                                     ^
    
    1 error
