1.32 + * Thrown by a method invocation on a proxy instance if its invocation
1.33 + * handler's {@link InvocationHandler#invoke invoke} method throws a
1.34 + * checked exception (a {@code Throwable} that is not assignable
1.35 + * to {@code RuntimeException} or {@code Error}) that
1.36 + * is not assignable to any of the exception types declared in the
1.37 + * {@code throws} clause of the method that was invoked on the
1.38 + * proxy instance and dispatched to the invocation handler.
1.39 + *
1.40 + * <p>An {@code UndeclaredThrowableException} instance contains
1.41 + * the undeclared checked exception that was thrown by the invocation
1.42 + * handler, and it can be retrieved with the
1.43 + * {@code getUndeclaredThrowable()} method.
1.44 + * {@code UndeclaredThrowableException} extends
1.45 + * {@code RuntimeException}, so it is an unchecked exception
1.46 + * that wraps a checked exception.
1.47 + *
1.48 + * <p>As of release 1.4, this exception has been retrofitted to
1.49 + * conform to the general purpose exception-chaining mechanism. The
1.50 + * "undeclared checked exception that was thrown by the invocation
1.51 + * handler" that may be provided at construction time and accessed via
1.52 + * the {@link #getUndeclaredThrowable()} method is now known as the
1.53 + * <i>cause</i>, and may be accessed via the {@link
1.54 + * Throwable#getCause()} method, as well as the aforementioned "legacy
1.55 + * method."
