Rundeck jobs fail to execute sometimes

[sharadr]

Environment:
Rundeck 1.4.4-dev connected to Oracle.

The job dispatch "hangs" with no output to the console.

In the catalina.out , the following error appears:
ERROR: Unable to start Job execution: failed to lookup Exception object from job data map: id: 497
java.lang.RuntimeException: failed to lookup Exception object from job data map: id: 497

After discussing with greg,:

There is a race condition when starting a job. the execution is created, but not flushed to the DB when the processing thread starts, so it fails to find it

This happens with MySQL on 1.4.3 as well.

I wasn't able to reproduce with mysql, but I confirmed the issue appears fixed for Oracle
