Hi Erik,

Actually, this is a bug in JDOImplHelper. It is missing a
doPrivileged around calling getDateTimeInstance.

The permissions you mention should be assigned to the JDO jar, if
needed at all. We need to look at the implementation here and decide
if getDateTimeInstance is really needed or if there is some other way
to get this functionality.

Can you please file a JIRA?

Thanks,

Craig
