public class UndeclaredThrowableException

extends java.lang.RuntimeException

This exception class is thrown by a Proxy instance if the invoke 55 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 java.lang.Error or java.lang.RuntimeException, which are unchecked.

1.3
