The reason of this failure is that `disconnect` call in JNDI `DnsClient` fails to rebind the datagram socket to the original port during `disconnect` call (the failure is in `DatagramChannel::repairSocket`).

Can you add `@bug  8265309` to com/sun/jndi/dns/ConfigTests/Timeout.java since this is a product change?
