Name

ExecutionException

Synopsis

An exception of this type is like a checked wrapper around an arbitrary exception thrown while executing a task. The get( ) method of a Future object, for example, throws an ExecutionException if the call( ) method of a Callable throws an exception. ExecutionException may also be thrown by ExecutorService.invokeAny( ). Use the Throwable.getCause( ) method to obtain the exception object that the ExecutionException wraps.
