    style changes are great but would it be possible to separate them from 
changes to functionality? that way it becomes easier to understand changes that 
are made when going through the version control log


> optimize the finish() of Send/RecvWorker in QuorumCnxManager and remove 
> testInitiateConnection() and formates some codes

> 1.the finish() of Send/RecvWorker in QuorumCnxManager changes to 
> double-checked lock style 
> [https://en.wikipedia.org/wiki/Double-checked_locking]
> ,a trivial code changes implement a smaller granularity lock to have a better 
> perfermance in too fierce multithread situation.
> 2.testInitiateConnection() is redundant test function which is only used in 
> TestCase,so I refactor it.
> 3.some codes don't abide to Java Programme Specification ,so I lift a finger 
> to format them
