* The remote interface is allowed to have superinterfaces. Use of interface
* inheritance is subject to the RMI-IIOP rules for the definition of remote
* interfaces.
*
* Verify the following:
*
* An RMI remote interface defines a Java interface that can be invoked
* remotely. A Java interface is a conforming RMI/IDL remote interface if:
*
* 1. The interface is or inherits from java.rmi.Remote either directly or
* indirectly.
*
* 2. All methods in the interface are defined to throw
* java.rmi.RemoteException or a superclass of java.rmi.RemoteException.
* Throughout this section, references to methods in the interface include
* methods in any inherited interfaces.
*
* 3. Method arguments and results may be of any types. However at run-time,
* the actual values passed as arguments or returned as results must be
* conforming RMI/IDL types (see "Overview of Conforming RMI/IDL Types" on
* page 28-2). In addition, for each RMI/IDL remote interface reference,
* the actual value passed or returned must be either a stub object or a
* remote interface implementation object (see "Stubs and remote
* implementation classes" on page 28-4).
*
* 4. All checked exception classes used in method declarations (other than
* java.rmi.RemoteException and its subclasses) are conforming RMI/IDL
* exception types (see "RMI/IDL Exception Types" on page 28-5)1
*
* 5. Method names may be overloaded. However, when an interface directly
* inherits from several base interfaces, it is forbidden for there to be
* method name conflicts between the inherited interfaces. This outlaws the
* case where an interface A defines a method "foo," an interface B also
* defines a method "foo," and an interface C tries to inherit from both A
* and B.
*
* 6. Constant definitions in the form of interface variables are permitted.
* The constant value must be a compile-time constant of one of the RMI/IDL
* primitive types or String.
*
* 7. Method and constant names must not cause name collisions when mapped to
* IDL (see "Names that would cause OMG IDL name collisions" on page 28-9).
*
* The following is an example of a conforming RMI/IDL interface definition:
* // Java
* public interface Wombat extends java.rmi.Remote {
* String BLEAT_CONSTANT = "bleat";
* boolean bleat(Wombat other) throws java.rmi.RemoteException;
* }
*
* While the following is an example of a non-conforming RMI/IDL interface:
* // Java
* // IllegalInterface fails to extend Remote!!
* public interface IllegalInterface {
* // illegalExceptions fails to throw RemoteException.
* void illegalExceptions();
* }

/**
* Method parameters checked for RMI-IIOP compliance test.
* Verify the following:
*
* The home/remote interface methods arguments types must be legal types for
* RMI-IIOP. This includes primitives, value types, and interfaces. This
* means that their arguments must be of valid types for RMI-IIOP.
*
* 28.2.4 RMI/IDL Value Types
* An RMI/IDL value type represents a class whose values can be moved
* between systems. So rather than transmitting a reference between systems,
* the actual state of the object is transmitted between systems. This
* requires that the receiving system have an analogous class that can be
* used to hold the received value. Value types may be passed as arguments
* or results of remote methods, or as fields within other objects that are
* passed remotely. A Java class is a conforming RMI/IDL value type if the
* following applies:
*
* 1. The class must implement the java.io.Serializable interface, either
* directly or indirectly, and must be serializable at run-time. It may
* serialize references to other RMI/IDL types, including value types
* and remote interfaces.
* 2. The class may implement java.io.Externalizable. (This indicates it
* overrides some of the standard serialization machinery.)
* 3. If the class is a non-static inner class, then its containing class
* must also be a conforming RMI/IDL value type.
* 4. A value type must not either directly or indirectly implement the
* java.rmi.Remote interface. (If this were allowed, then there would
* be potential confusion between value types and remote interface
* references.)
* 5. A value type may implement any interface except for java.rmi.Remote.
* 6. There are no restrictions on the method signatures for a value type.
* 7. There are no restrictions on static fields for a value type.
* 8. There are no restrictions on transient fields for a value type.
* 9. Method, constant and field names must not cause name collisions when
* mapped to IDL (see "Names that would cause OMG IDL name collisions"
* on page 28-9).
*
* Here is an example of a conforming RMI/IDL value type:
* // Java
* public class Point implements java.io.Serializable {
* public final static int CONSTANT_FOO = 3+3;
* private int x;
* private int y;
* public Point(int x, y) { ... }
* public int getX() { ... }
* public int getY() { ... }
* }
*
* 28.2.4.1 The Java String Type
* The java.lang.String class is a conforming RMI/IDL value type following
* these rules. Note, however, that String is handled specially when mapping
* Java to OMG IDL (see "Mapping for java.lang.String" on page 28-18).
