Xuefu Zhang commented on HIVE-7409:
-----------------------------------
[~ozawa] Thanks for pointing out the potential deadlock issue in JDK. However,
according to the referenced JDK issue, the deadlock is happening between
getAnnotations() and isAnnotationPresent(). Since Hive only calls the first
method, is it possible that Hive doesn't suffer so said deadlock problem?
> Add workaround for a deadlock issue of Class.getAnnotation()

> [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.
