>                 URL: http://issues.apache.org/jira/browse/HARMONY-985
>             Project: Harmony
>          Issue Type: Bug
>          Components: Non-bug differences from RI
>            Reporter: Richard Liang

> For the constructor java.util.Formatter.Formatter(Appendable a):
> If we pass a null to j.u.Formatter.Formatter(Appendable a), when we try to get the destination
of the formatter's output by calling formatter.out(), RI will thrown a java.util.FormatterClosedException.
But according to the specification,  the destination should be a StringBuilder. 
> Harmony complies with  the specification, but RI breaks the specification.
> References:
> 1) Specification:
> public Formatter(Appendable a)
>    Constructs a new formatter with the specified destination.
>    The locale used is the default locale for this instance of the Java virtual machine.
>    Parameters:
>        a - Destination for the formatted output. If a is null then a StringBuilder will
be created.
> 2) The following test passes on Harmony, but fails on RI.
>    public void test_ConstructorLjava_lang_Appendable() {
>        Formatter formatter = new Formatter((Appendable) null);
>        Appendable out = formatter.out();
>        assertTrue(out instanceof StringBuilder);
>    }
