      Description

      I found serious problems with datanucleus code when using JDK7, resulting in some sort of exception being thrown when datanucleus code is entered.

      I tried source=1.7, target=1.7 with JDK7 as well as source=1.6, target=1.6 with JDK7 and there was no visible difference in that the same unit tests failed.

      I tried upgrading datanucleus to 3.0.1, as per HIVE-2084.patch, which did not fix the failing tests.

      I tried upgrading datanucleus to 3.1-release, as per the advise of http://www.datanucleus.org/servlet/jira/browse/NUCENHANCER-86, which suggests using ASMv4 will allow datanucleus to work with JDK7. I was not successful with this either.

      I tried upgrading datanucleus to 3.1.2. I was not successful with this either.

      Regarding datanucleus support for JDK7+, there is the following JIRA

      http://www.datanucleus.org/servlet/jira/browse/NUCENHANCER-81

      which suggests that they don't plan to actively support JDK7+ bytecode any time soon.

      I also tested the following JVM parameters found on

      http://veerasundar.com/blog/2012/01/java-lang-verifyerror-expecting-a-stackmap-frame-at-branch-target-jdk-7/

      with no success either.

      This will become a more serious problem as people move to newer JVMs. If there are other who have solved this issue, please post how this was done. Otherwise, it is a topic that I would like to raise for discussion.
