JobManager.isIdle() is not working as expected

[laeubi]

what I do:

private void waitForAnyJobs(IJobManager manager) {
		debug("Suspend JobManager...");
		manager.suspend();
		debug("Wait for JobManager become idle...");
		while (!manager.isIdle()) {
			Thread.onSpinWait();
		}
		debug("JobManager is idle... no new jobs will run!");
	}

what I see:

After calling waitForAnyJobs I still see jobs running:

Job Periodic workspace save.(7) aboutToRun...
Job Periodic workspace save.(7) running...
Job Building(4) sleeping...
Project component was found
Suspend JobManager...
Wait for JobManager become idle...
Job Periodic workspace save.(7) done...
JobManager is idle... no new jobs will run!
Job Registry event dispatcher(40) scheduled...
Job Updating index names(16) scheduled...
Job Java indexing... (38) done...
Job Compacting resource model(14) done...
Job Building(4) done...
Job Reporting encoding changes.(9) done...
Job Flushing content description cache.(11) done...

I checked with debugger that no (user) code calls resume... so my assumption would be that jobs are schedule but never complete afterwards, but what I see in the log is done, and even schedule/done results.

You probably run into "sleeping" jobs that were scheduled with a delay or may be jobs blocked by others.
So you can try:

• suspend job manager
• cancel every job
• loop a bit till jobManager.find(null) returns nothing, there can be jobs that don't react on cancel()

        Job.getJobManager().cancel(null);
        Job.getJobManager().suspend();
        if(!Job.getJobManager().isIdle()){
        Job[] jobs = Job.getJobManager().find(null);
        for (Job job : jobs) {
           // log still running job
