Uncaught exception print in stderr when timeout

[javierfreire]

Describe the bug

When a timeout occurs, the behavior is correct but, sometimes, a race condition happens and an unhandled exception is thrown.

To Reproduce

public class TimeoutTest {

    public static void main(String[] args) {
        ProcBuilder builder = new ProcBuilder("bash",  "-i", "-c", "echo hello").withTimeoutMillis(1);

        try {
            builder.run();
        } catch (TimeoutException ex) {
            //OK
        }
    }
}

Expected behavior

No uncaught exception should be printed in stderr.

Actual Behaviour

These traces are printed by stderr

I didn't expect any uncaught exception.

Context

I did use Ubuntu.
