Kevan Jahanshahi updated UNOMI-572:
-----------------------------------
Description:
The SchedulerService implementation is part of the *unomi-services* bundle, so
in case somebody is editing a configuration file like this one:
{code:java}
org.apache.unomi.services {code}
The SchedulerService will be restarted, and some tasks/timers will be lost
during the process, because not all tasks/timers are coming from the
*unomi-services* bundle.
There is other bundles that would need to be notify about that restart to be
able to re-register their tasks and timers.
Currently those tasks/timers coming from other bundles are lost, and this is
causing major Unomi runtime instabilities.
For exemple: Recently we added a JSON Schema service that have a task to reload
schemas from ES directly into RAM. This task is lost in case of conf editing on
the mentioned conf, making JSON Schemas not reloaded anymore.
