I agree with Vyom here.

Other solutions that have been investigated - such as only
setting the connection to null when its ref count reaches zero
now seem to complex (read: too risky because over the complexity
threshold) to me.

Maybe the best thing to do here is to stick to Vyom original's
idea, but declare conn final and do all the necessary (small)
cleanup that goes with it? Possibly also add a comment saying
that CommunicationException will be thrown if some other thread
uses the LdapClient after forceClose has been closed...
