Description

Consider the following:

class M extends HashMap<String,Number> {
  private void setFoo(foo) { print foo }
}
@groovy.transform.CompileStatic
void test() {
  def map = new M()
  map.foo = 123
  print map.foo
}

Assignment expression "map.foo = 123" shows error "[Static type checking] - Cannot assign value of type int to variable of type java.lang.Object". Adding cast to Object changes the message to "Cannot assign value of type java.lang.Object to variable of type java.lang.Object".
