Class UndeclaredThrowableException

Implemented Interfaces:
Serializable

public class UndeclaredThrowableException

This exception class is thrown by a Proxy instance if the invoke method of that instance's InvocationHandler attempts to throw an exception that not declared by the throws clauses of all of the interface methods that the proxy instance is implementing.

When thrown by Proxy, this class will always wrap a checked exception, never Error or RuntimeException, which are unchecked.
