Task scheduler -> scheduled tasks: missing class

Description
When testing, I created a class for scheduler and scheduled a task. Then I deleted the class and went to the task scheduler -> scheduled tasks tab. The server threw 500 and no tasks were on the agenda (sorry, don't have the stack trace).
I think IdM should be prepared for this situation. and show meaning full results (For example show the scheduled task with a red background). This situation can happen for example when migrating to a new version.

I agree, i've added this check to authorization evaluators, i'll add it here too.

ClassNotFoundException is thrown in read job detail method => i don't have task detail to show him in table in some disabled mode, so I added check and removed task type is automatically removed from scheduler, if ClassNotFoundException occurs.

I created a custom class TestTask. I scheduled it (to start every 5 sec), stopped the server, removed the task and started the server again. The server failed to load with the following exception. The problem may be, that the task was already waiting in the queue (I have no automatic task execution).

Then I tried again, but this time I scheduled the task to run in future (one time start) and the queue was empty. This exception was thrown during the startup as WARNing, the server successfully loaded, and the task is not visible in the scheduled tasks category.

So the problem persists, if the task is waiting in the queue - but I am not sure if that is that much important? Or even if it can be easily solved as it is some quartz/spring internal thing.

Thx for feedback! I'll try to add another check, when trigger is executed.

I've added task type check before scheduler starts.
Could you pls do a feedback once again?

It works now. When there was a scheduled task waiting in the queue and I removed the class, the task in the queue turned to failed with the code LONG_RUNNING_TASK_NOT_FOUND (which I think is good - the administrator can see that something happened). The task disappeared from the scheduled tasks category - here it would be better if it also was shown with a failed status, but we discussed that before.
Good job
