> While testing with Java 8 I found that org.apache.openjpa.lib.util.concurrent.NullSafeConcurrentHashMap
doesn't work on Oracle Java 8 as java.util.ConcurrentHashMap was completely rewritten and
it doesn't like playing with our extension. 
> I'm not sure what the correct solution for this JIRA will be, but I wanted to get it
documented. I did a small amount of searching and it appears that NullSafeConcurrentHashMap
isn't used very much in our code base so it might be easiest to remove those references and
deprecate the data structure. That being said, we'll still need to fix this data structure
as it is possible that a user of OpenJPA pulled this structure into app code.
