Undescriptive error message when calling method with void argument

Test case:

void f(int i) {
}
void m() {
  f(f(3));
}

JastAddJ gives the following error message:

Test.java:5:
  Semantic Error: no method named f(void) in Test matches. However, there is a method f(int)

It would be better if JastAddJ simply said that the argument f(3) is void and calling a method with a void argument is not allowed.
