StackOverflowError on computing the GLB

    XMLWordPrintable

    Details

    • Subcomponent:
    • Introduced In Version:
      9
    • CPU:
      generic
    • OS:
      generic

      Description

      A DESCRIPTION OF THE PROBLEM :
      The following program leads to an infinite loop on javac while computing the GLB between two types.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      class Main {
        static public final C<? super A<Double>> test() {
          final C<? super A<Double>> x = null;
          x.f = null;
          return x;
        }
      }

      class A<T> {}

      abstract class B<F, B extends F> {}

      abstract class C<N extends A<Number>> {
        public B<? extends N, ? extends N> f;
      }

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      The compiler should reject the above program as the type argument of C (lines 2, 3) does not respect the bound of type variable N.
      ACTUAL -

      Main.java:2: error: type argument ? super A<Double> is not within bounds of type-variable N
        static public final C<? super A<Double>> test() {
                              ^
        where N is a type-variable:
          N extends A<Number> declared in class C
      Main.java:3: error: type argument ? super A<Double> is not within bounds of type-variable N
          final C<? super A<Double>> x = null;
                  ^
        where N is a type-variable:
          N extends A<Number> declared in class C
      2 errors
