The StandardMBean(Object implementation, Class mbeanInterface) constructor
throws NullPointerException instead of NotCompliantMBeanException if the
given implementation does not implement a management interface.
The following test fails running on 1.5.0-beta-b18 but passes running on
1.5.0-beta-b17. See below the test source and execution log:

---Test.java--------------------------------------------------------------------
import javax.management.NotCompliantMBeanException;
import javax.management.StandardMBean;

public class Test {
    public static void main (String args[] ) {
try {
new StandardMBean(new Object(), null);
} catch (NotCompliantMBeanException e) {
System.out.println("Ok");
        } catch (Exception e) {
e.printStackTrace();
}
    }
}
