Hi all,
I am observing an issue in production which looks to me like a race
condition, but I am unable to reproduce it so far.
The exception is:
java.lang.IllegalStateException: Existing Configuration with pid
factoryPid.a5b6fe71-556c-4ce9-b09c-c19542586fc5 has had its properties set
to null and location changed. We expected a delete event first.

What is happening:
I am creating configurations in Karaf (4.0.5) using ConfigAdmin:
Configuration configuration = configAdmin.createFactoryConfiguration(
"factoryPid", null);
configuration.update(dictionary);
It is possible that due to validation shortly after the same config is
deleted:
configAdmin.listConfigurations("(service.factoryPid=factoryPid)"
)[0].delete()
My theory is that the update is still processing while it is already
deleted again, and then the scr listener complains.
Ideas?
Best regards,
Fabian
