0N/A/**
0N/A * A <code>RemoteException</code> is the common superclass for a number of
0N/A * communication-related exceptions that may occur during the execution of a
0N/A * remote method call. Each method of a remote interface, an interface that
0N/A * extends <code>java.rmi.Remote</code>, must list
0N/A * <code>RemoteException</code> in its throws clause.
0N/A *
0N/A * <p>As of release 1.4, this exception has been retrofitted to conform to
0N/A * the general purpose exception-chaining mechanism. The "wrapped remote
0N/A * exception" that may be provided at construction time and accessed via
0N/A * the public {@link #detail} field is now known as the <i>cause</i>, and
0N/A * may be accessed via the {@link Throwable#getCause()} method, as well as
0N/A * the aforementioned "legacy field."
0N/A *
0N/A * <p>Invoking the method {@link Throwable#initCause(Throwable)} on an
0N/A * instance of <code>RemoteException</code> always throws {@link
0N/A * IllegalStateException}.
