>             Project: Sling
>          Issue Type: Improvement
>          Components: Event
>    Affects Versions: Event 4.3.14

> Although in general every serializable complex class can be passed to {{JobManager.addJob}} as property it cannot be properly deserialized.
> Once the job is actually processed the log emits
> {code}
> org.apache.sling.event.impl.jobs.JobManagerImpl Unable to read job from /var/eventing/jobs/assigned/...., exception: java.lang.Exception: Unable to deserialize property 'customType', cause: java.lang.ClassNotFoundException: <FQCN>
> {code}
> The reason is that for deserialization a different classloader is used (the one from the bundle https://github.com/apache/sling-org-apache-sling-event) than during serialization (the one of the custom bundle which scheduled the job).
> This limitation should either be lifted or clearly documented.
