[jira] [Commented] (HBASE-10547) TestFixedLengthWrapper#testReadWrite occasionally fails with the IBM JDK

["Andrew Purtell (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-10547?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13902252#comment-13902252 ] 

Andrew Purtell commented on HBASE-10547:
----------------------------------------

Kind of a WTF at first glance. I did try substituting the assertArrayEquals call with assertTrue(Bytes.equals(..)) with no difference, I wasn't expecting one. Any ideas [~ndimiduk]?
