> While trying to enable tests from
> org.apache.harmony.beans.tests.java.beans.StatementTest I have faced
> the strange problem. It seems that while building Statement for
> accessing array elements RI doesn't check the number of parameters of
> get() method. It simply takes the value of first argument, converts it
> to integer and does nothing more. Following (IMHO invalid) tests pass
> on RI:
> Test1:
> Object[] array = new Object[] { "test" };
> Statement t = new Statement(array, "get", new Object[] {
>        new Integer(0), new Object() });
> t.execute();
> Test2:
> Object[] array = new Object[] { "test" };
> Statement t = new Statement(array, "get", new Object[] {
>        new Integer(0), new Object(), new Integer[] {1,2,3,4,5,6},
>        new java.util.GregorianCalendar(), "mama mila ramu" });
> t.execute();
> The spec states the following:
> "The method names 'get' and 'set' defined in the java.util.List
> interface may also be applied to array instances, mapping to the
> static methods of the same name in the Array class."
> Therefore, since java.util.List defines 'get' method with excatly one
> integer argument I suppose the correct test should look like:
> Test3:
> Object[] array = new Object[] { "test" };
> Statement t = new Statement(array, "get", new Object[] {
>        new Integer(0) });
> t.execute();
> And Test1 and Test2 should throw NoSuchMethodException as our
> implementation does.
> So, the behavior of our implementation differs from RI. But RI's behavior looks unnatural
in this case. It was decided [1] we should keep our behavior.
