public class UndeclaredThrowableException
extends RuntimeException

Thrown by a method invocation on a proxy instance if its invocation handler's `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.

Since:
  JDK1.3

  `InvocationHandler`, Serialized Form
