Maybe we can break it, but this new property is following the same pattern I
think as the neighbouring file
src/java.rmi/share/classes/sun/rmi/transport/tcp/TCPChannel.java when it reads
the system props. I see Integer.getInteger handles the obvious Exceptions, so
specifying a strange value does not immediately break us.
If there's more protection needed then we have various other places to apply it
that might need separate follow-up if you think there's a case?
