Thanks all for chiming in. I filed HBASE-15624 Move master
branch/hbase-2.0.0 to jdk-8 only to act on the decision made here.

+1 on jdk8 only. Bunch of code could be refactored with jdk8's new
features, new classes and new methods.
For example, most 'get->putIfAbsent->checkAndCleanUp' and 'get->lock->get
again->put->unlock' can be replaced by computeIfAbsent.

I don't think it'll actually speed up tests much. In precommit we only
check one jdk for unit tests and in postcommit we do them in parallel.

As a side benefit, only testing one jdk would seriously speed up test runs.

we'll need to get a feature into yetus that can change multijdk
settings by branch, presuming that change will result in us either
taking on jdk8-only dependencies or direct use of jdk8-only features.
