Carsten Ziegeler commented on SLING-1066:
-----------------------------------------

This is a result of the new class loading architecture - before we had the dynamic import package which caused the eventing bundle to reload

> The job handler holds all jobs in memory (loads persisted jobs on startup). If a job event uses a public class from a bundle, and such a job is in the queue while the bundle gets updated, the job still uses the old class. As the bundle and maybe other bundles are wired to the updated version, this might result in class cast exceptions.
