System.exit in Java Thread

Question

My main thread created a new thread And when the new thread call System.exit(-1),my main thread be closed. How can I handle the exit code and keep the main thread alive?

PS. the new thread will call some method in other .jar file, so I can't modify it.

Answer 1

You can't.

Terminates the currently running Java Virtual Machine. The argument serves as a status code; by convention, a nonzero status code indicates abnormal termination.

That's the javadoc.

So the method will terminate the entire JVM. Not just the thread....
