Description

Reason	Tests
FindBugs	module:hbase-server
Boxed value is unboxed and then immediately reboxed in org.apache.hadoop.hbase.security.access.SecureBulkLoadEndpoint.incrementUgiReference(UserGroupInformation) At SecureBulkLoadEndpoint.java:then immediately reboxed in org.apache.hadoop.hbase.security.access.SecureBulkLoadEndpoint.incrementUgiReference(UserGroupInformation) At SecureBulkLoadEndpoint.java:[line 268]

Looking at branch-2 and master I suspect we're doing the same wasteful operation but findbugs can't see it through the lambda definition.
