Guillaume Nodet commented on ARIES-441:
---------------------------------------
I think the problem happens under the following conditions:
* the persistent id has no configuration in the ConfigAdmin
* there are multiple ManagedService(s) registered for the same pid
That's my analysis looking at the code at [1].
I think you should ask the equinox guys about that but I don't have any work
around for that unfortunately.
