      Description



      Name: laC46010 Date: 08/26/99



      Javac (jdk1.1-jdk1.3beta) doesn't detect an unassigned local blank final variable.
      Inner Classes Specification, section "Blank finals and final local variables", says:

      "A blank final must be assigned an initial value, at most once."

      See reduced JCK test source and logs below:

          }
      }
