| 29 | * A <code>ServerCloneException</code> is thrown if a remote exception occurs | ||
| 30 | * during the cloning of a <code>UnicastRemoteObject</code>. | ||
| 31 | * | ||
| 32 | * <p>As of release 1.4, this exception has been retrofitted to conform to | ||
| 33 | * the general purpose exception-chaining mechanism. The "nested exception" | ||
| 34 | * that may be provided at construction time and accessed via the public | ||
| 35 | * {@link #detail} field is now known as the <i>cause</i>, and may be | ||
| 36 | * accessed via the {@link Throwable#getCause()} method, as well as | ||
| 37 | * the aforementioned "legacy field." | ||
| 38 | * | ||
| 39 | * <p>Invoking the method {@link Throwable#initCause(Throwable)} on an | ||
| 40 | * instance of <code>ServerCloneException</code> always throws {@link | ||
| 41 | * IllegalStateException}. | ||
