/**
* Thrown by a method invocation on a proxy instance if its invocation
* handler's {@link InvocationHandler#invoke invoke} method throws a
* checked exception (a Throwable that is not assignable
* to RuntimeException or Error) that
* is not assignable to any of the exception types declared in the
* throws clause of the method that was invoked on the
* proxy instance and dispatched to the invocation handler.
*
*
An UndeclaredThrowableException instance contains
* the undeclared checked exception that was thrown by the invocation
* handler, and it can be retrieved with the
* getUndeclaredThrowable() method.
* UndeclaredThrowableException extends
* RuntimeException, so it is an unchecked exception
* that wraps a checked exception.
*
*
As of release 1.4, this exception has been retrofitted to
* conform to the general purpose exception-chaining mechanism. The
* "undeclared checked exception that was thrown by the invocation
* handler" that may be provided at construction time and accessed via
* the {@link #getUndeclaredThrowable()} method is now known as the
* cause, and may be accessed via the {@link
* Throwable#getCause()} method, as well as the aforementioned "legacy
* method."
