-----------------------------------
Hi [~yuzhih...@gmail.com] , nowadays, kylin's minimum java version requirement
is sitll 1.7, when it comes to 1.8, we can replace ReentrantReadWriteLock in
class AutoReadWriteLock with StampedLock.
> Consider replacing ReentrantReadWriteLock with StampedLock

> Assignee: jiatao.tao
> Priority: Major
> Fix For: v2.5.0

> ReentrantReadWriteLock's are only the right solution when there is long hold
> time due to expensive I/O.
> It is expensive for readers.
> We should see if the lighter {{StampedLock}} can be used instead.
