ZOOKEEPER-1011:fix Java Barrier Documentation example's race condition
issue and polish up the Barrier Documentation
- This patch fix the race condition of double barrier and avoid the herd
effect.
- To focus on the core logic and keep the codes short and clean,don't
consider some parameters check,connect loss,the timeout for wait ....etc.The
thoughtful codes can be found in the implements of `DistributedDoubleBarrier`
of `curator-recipes`.
- For test,you can change the `QTY` in the barrierTest from small
one(1,2,3) to large one(1000,5000,10000),then observer the printed log to check
the correctness of this patch.
