This is because if there is a THREAD_LOCAL for the loop, it would end up
being an infinite recursive call within the thread. However, it's technically
possible to have THREAD_LOCAL for part of the cycle. I have reopened this
JIRA: https://issues.apache.org/jira/browse/APEXCORE-262. We will tackle this
in the future.
