> Given a test case [1], RI passes it while HARMONY fails and throws a java.lang.NullPointerException.
> According to Java Spec, if the argument cd does not represent a MemoryUsage with the attributes described below, it should throw a java.lang.IllegalArgumentException.
> Attribute Name  	Type
> init                           java.lang.Long
> used                       java.lang.Long
> committed             java.lang.Long
> max                        java.lang.Long
> [1] Test Case:
> public void test_from() throws Exception {
>     String[] names = { "init", "used", "committed" };
>     Object[] values = { null, null, null };
>     OpenType[] types = { SimpleType.LONG, SimpleType.LONG, SimpleType.LONG };
>     CompositeType compositeType = getCompositeType(names, types);
>     CompositeData data = new CompositeDataSupport(compositeType, names, values);
>     try {
>         MemoryUsage.from(data);
>         fail("should throw IllegalArgumentException");
>     } catch (IllegalArgumentException e) {
>         // Expected
>     }
