Is the volatile keyword required for fields accessed via a ReentrantLock?

It's safe without volatility. ReentrantLock implements Lock, and the docs for Lock include this:

All Lock implementations must enforce the same memory synchronization semantics as provided by the built-in monitor lock, as described in The Java Language Specification, Third Edition (17.4 Memory Model):

  • A successful lock operation has the same memory synchronization effects as a successful Lock action.
  • A successful unlock operation has the same memory synchronization effects as a successful Unlock action.
