Threadsafety of SimpleTimeLimiter

Question

I want to use com.google.common.util.concurrent.SimpleTimeLimiter from guava in my server applications.

Can I create a singleton instance of SimpleTimeLimiter for the use in several classes?

Is the call of its method callWithTimeout() thread safe?

Answer 1

Sources of SimpleTimeLimiter looks perfectly thread safe for me. There are actually no place there to break thread safety, while executor you are passing is thread safe.
