Review request for 6844054: (bf) Eliminate dependency on javax.management.ObjectName

[Alan Bateman]

Mandy - you do mind reviewing this change to eliminate the dependency in 
java.nio on javax.management.ObjectName that we've chatted about. The 
changes move the creation of the management interfaces to 
ManagementFactoryHelper. The webrev is here:

Thanks,
