Maybe I'm missing something since the bug is not viewable to the community, 
but, if I'm reading properly, this design by itself is not quite right, and 
the fix of 200 msec selector timeout is just a band-aid solution.

Shouldn't it be registering interestOps for reading on the existing 
connections and accepting connections from the server socket in the selector? 
Otherwise why use any selector in the first place if it's not really selecting 
across all the right sockets and right events on them?

Regards,
Matthew.
