IdStory Identity Manager

Support remove running events without server restart is implemented. Running events can be removed and event's owner is not blocked from another processing.
Note: The only way, how can be reproduced is to create some processor, which never ends - e.g. provisioning to target system without timeout (running event was removed correctly other ways).

I've improved default event configuration for the slightly speeding up event processing (~ 2x) and prevent to exhaust system resources:

• Event executor core pool size uses CPU count + 1 as default. Was configured CPU count * 2 => too overload
  

  scheduler.event.executor.corePoolSize=<CPU count + 1> 

• Set higher queue capacity - prevent to prepare events repetitively and use additional threads till maxPoolSize is exhausted.
  

  scheduler.event.executor.queueCapacity=1000 

• prepared (created) events are not loaded, when the previously loaded events still running

The first two point can be configured without release is needed.

I've added:

• new bulk action for executing account management for the selected identity - usable for testing or e.g. if some accounts are deleted manually and has to be created again. Available for system admins (SYSTEM_ADMIN permission)
• re-save identity bulk action was hidden (will be removed in 10.x version) - new action for executing provisioning only was created.

Could you do a review please?

For testing I use same behavior as you use in test. I try remove parents events, children events and from both sides it is working as I except. Simulate this problem is really hard (event simulate this in tests).

Also I tests some another magic with events, eq: generate hundrets of events and then remove all and etc.

Behavior with clean cache works correctly now.
