1.47 - * Processes a method invocation on a proxy instance and returns

1.52 - * @param proxy the proxy instance that the method was invoked on
1.53 - *
1.54 - * @param method the {@code Method} instance corresponding to
1.55 - * the interface method invoked on the proxy instance. The declaring
1.56 - * class of the {@code Method} object will be the interface that
1.57 - * the method was declared in, which may be a superinterface of the
1.58 - * proxy interface that the proxy class inherits the method through.
1.59 - *
1.60 - * @param args an array of objects containing the values of the
1.61 - * arguments passed in the method invocation on the proxy instance,
1.62 - * or {@code null} if interface method takes no arguments.
1.63 - * Arguments of primitive types are wrapped in instances of the
1.64 - * appropriate primitive wrapper class, such as
1.65 - * {@code java.lang.Integer} or {@code java.lang.Boolean}.
1.66 - *
1.67 - * @return the value to return from the method invocation on the
1.68 - * proxy instance. If the declared return type of the interface
1.69 - * method is a primitive type, then the value returned by
1.70 - * this method must be an instance of the corresponding primitive
1.71 - * wrapper class; otherwise, it must be a type assignable to the
1.72 - * declared return type. If the value returned by this method is
1.73 - * {@code null} and the interface method's return type is
1.74 - * primitive, then a {@code NullPointerException} will be
1.75 - * thrown by the method invocation on the proxy instance. If the
1.76 - * value returned by this method is otherwise not compatible with
1.77 - * the interface method's declared return type as described above,
1.78 - * a {@code ClassCastException} will be thrown by the method
1.79 - * invocation on the proxy instance.

1.82 - * invocation on the proxy instance. The exception's type must be

1.84 - * {@code throws} clause of the interface method or to the
1.85 - * unchecked exception types {@code java.lang.RuntimeException}
1.86 - * or {@code java.lang.Error}. If a checked exception is
1.87 - * thrown by this method that is not assignable to any of the
1.88 - * exception types declared in the {@code throws} clause of
1.89 - * the interface method, then an
1.90 - * {@link UndeclaredThrowableException} containing the
1.91 - * exception that was thrown by this method will be thrown by the
