Restart not working properly with Oracle. This is a weird one. Some people seem to have the problem and others not (see forum thread, dating from pre-m3: http://forum.springframework.org/showthread.php?t=46821).

Actually, it looks completely deterministic (since m5 - before that it might have been changing day to day with the implementation of the daos). The FIND_JOBS query in the JobInstanceDao fails to find the previous execution because of a comparison failure (Oracle treats null and empty string different than other platforms). We had a bug like this a while ago, and I thought it was fixed, but it looks like it crept back in (in a different place).

Make JOB_KEY non-empty when there are no JobParamaters.
