| /** |
| * @assertion Future<Isolate> spawn(void entryPoint(message), message, |
| * {bool paused: false, bool errorsAreFatal, SendPort onExit, SendPort onError}) |
| * |
| * The argument entryPoint specifies the entry point of the spawned isolate. |
| * It must be a top-level function or a static method that takes one argument - |
| * that is, one-parameter functions that can be compile-time constant function |
| * values. It is not allowed to pass the value of function expressions or |
| * an instance method extracted from an object. |
| * |
| * The entry-point function is invoked with the initial message. Usually |
| * the initial message contains a SendPort so that the spawner and spawnee can |
| * communicate with each other. |
| * ... |
| * Returns a future that will complete with an Isolate instance if |
| * the spawning succeeded. It will complete with an error otherwise. |
| * |
| * @description Checks that if entryPoint is instance method, then returned |
| * Future instance completes with error |
