----------------------------------------------
I submitted another patch for fixing the style, however, I found the failures
in
[complie|https://builds.apache.org/job/PreCommit-HBASE-Build/12854/artifact/patchprocess/patch-compile-hbase-server-jdk1.7.0_181.txt]
and
[unit|https://builds.apache.org/job/PreCommit-HBASE-Build/12854/artifact/patchprocess/patch-unit-hbase-server.txt]
logs should not be related.

logs, a very strange error jdk 7 incompatible with jdk 8 of
`maven-compiler-plugin:3.6.1:compile: java.lang.UnsupportedClassVersionError:
javax/tools/DiagnosticListener : Unsupported major.minor version 52.0`. I found
other JIRAs that works on branch-1 has the same issue, did the maven version
(3.6.1) has any problem with jdk 7 ?? or in the pom.xml (I didn't touch that)
has any issue with jdk 7 ? this also happened on the local compile as well

log, all unit tests completed but at the end of the test process, I saw a lots
of `ExecutionException The forked VM terminated without properly saying
goodbye. VM crash or System.exit called?` I found this [surefire
faq|http://maven.apache.org/surefire/maven-surefire-plugin/faq.html] and said
system.exit() at any time is not supported (I also found some other JIRAs that
works on branch-1 has this issue). So those Test classes called system.exit()
should not be related to this change, but just be curious, does anyone know how
to get it thru?
