Vladimir Rodionov commented on HBASE-13761:
-------------------------------------------

{quote}
org/apache/hadoop/hbase/util/UnsafeAccess.java
 Error	design	HideUtilityClassConstructor	Utility classes should not have a public or default
constructor.
{quote}

Checkstyle must be disabled for this class. Every class has default constructor. The error
is strange.
