As far as I understand RI simply take the first declared method. In
other words, if we swap constructors in the above example like this
public static class MyBean {
static String calledM = null;
public MyBean(Integer arg) {
calledM = "new2";
}
public MyBean(Object arg) {
calledM = "new1";
}
}
the result will be "PASS".

How does RI behave if there are three methods? does it alway selects less
specific?
