Undescriptive error message for void dereferencing

[Jesper Öqvist]

When dereferencing void JastAddJ should report a more descriptive error, similar to that of javac:

class Test {
        void f(int i) {
        }
        void m() {
                f(0x123).f(-11111);
        }
}

With JastAddJ I get the following error:

Test.java:5:
  Semantic Error: no method named f(int) in void matches.

Javac reports a more descriptive error:

Test.java:5: error: void cannot be dereferenced
                f(0x123).f(-11111);
                        ^
