Yes, you can run Thread

in Thread.UncaughtExceptionHandler.uncaughtException

... provided that it has Thread

not been launched before.

But it is not possible to run Thread

that was passed as an argument t

. It will (always) be Thread

, which has already been started and completed.



You can run the specified Thread

maximum once. If you try to run a second time, you get InvalidStateException

. Is always.

No, you cannot start the thread that threw the exception, as shown in your code. It has already been launched. This is like an exception. A thread cannot be started more than once.
