Class ReflectionUtil

java.lang.Object

org.apache.hive.common.util.ReflectionUtil

public class ReflectionUtil
extends Object

Same as Hadoop ReflectionUtils, but (1) does not leak classloaders (or shouldn't anyway, we rely on Guava cache, and could fix it otherwise); (2) does not have a hidden epic lock.
