Is it possible to run the java thread in UncaughtExceptionHandler?

Question

Is it possible to recover java thread by doing the next?

Thread.setDefaultExceptionHandler(new UncaughtExceptionHandler() {
    public void unchaughtException(Thread t, Throwable e) {
        t.start();
    }
});

Answer 1

Yes it is possible to run a Thread in a Thread.UncaughtExceptionHandler.uncaughtException ... provided that the Thread hasn't been started previously.

But it is NOT possible to start the Thread that was pass as the t argument. That will (always) be a Thread that has already been started and has terminated.

You can start a given Thread at most once. If you try to start one a second time you will get an InvalidStateException . Always.

Answer 2

No, you cannot run the thread that threw the exception, as shown in your code. It has already run. That's how it threw the exception. A thread cannot be started more than once.
