-----------------------------------

If my understanding is right, our current bylaw requires a +1 in order to commit. I don't
see a +1 yet.

> [JDK-7122142|https://bugs.openjdk.java.net/browse/JDK-7122142] mentions that there is
a race condition in getAnnotations. This problem can lead deadlock. The fix on JDK will be
merged on jdk8, but hive supports jdk6/jdk7 currently. Therefore, we should add workaround
to avoid the issue.
