Is there a way to get all the jobs started by the particular plugin in eclipse?

Is there a way to get all the jobs started by the particular plugin in eclipse? Here we run eclipse in command line mode. We start few jobs in a plugin. At some case the plugin terminates even before the job is completed. It has been decided to wait for all the jobs started by the particular plugin in Activator.stop(). I was wondering whether there's a possibility to get all the jobs started by a particular plugin.
