Several comments:

1. findPortUnreachableExc() can be put outside of the Future and called directly.

2. When a TimeoutException is caught from future.get(), I think this should be treated as a failure. We have already used
findPortUnreachableExc() to confirm PUE is available on this system and that port is not used by another process. If we still see timeout, it should be investigated. In fact, if the test succeeds in this case, it will never fail. Right?

3. Why not write 2 catch blocks here for each exception type?

  120         } catch (SocketTimeoutException | PortUnreachableException 
e) {
  121             if (e instanceof PortUnreachableException) {
  122                 return true;
  123             }
  124         }

Thanks
Max
