Description

I just discovered the @Immutable annotation and migrated some of my classes to it. Unfortunately, I realized that the behavior of the constructor changes slightly: For ordinary groovy beans, I used to get a MissingPropertyException when specifying a named parameter for a non-existing property. For @Immutable groovy beans, the parameter is silently ignored.
Here an example which shows the error:

@Immutable class ImmutablePerson {
    String name
}

class Person {
	String name
}

Person p = new Person(name: "uli"); // works fine
assert "uli" == p.name;
ImmutablePerson ip = new ImmutablePerson(name: "uli"); // works fine, too
assert "uli" == ip.name;

try {
  Person p2 = new Person(name: "uli", lastname: "heller"); // throws an exception, fine
  assert false;
} catch (MissingPropertyException mpe) {
  assert true;
}

try {
  ImmutablePerson ip2 = new ImmutablePerson(name: "uli", lastname: "heller"); // does not throw an exception
  assert false; // ... so it fails within this assertion
} catch (MissingPropertyException mpe) {
  assert true;
}
