UndeclaredThrowableException

UndeclaredThrowableException  extends RuntimeException

 

Thrown by a method invocation on a proxy instance if its invocation handler's invoke method throws a

checked exception 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

getUndeclaredThrowableException() method.

UndeclaredThrowableException extends RuntimeException, so it is an unchecked exception

that wraps a checked exception.

public interface InvocationHandler{

     public Object invoke(Object proxy, Method method, Object[] args) throws Throwable;
