Stephan Siano commented on ARIES-1109:
--------------------------------------
I found this behaviour with the 1.0.0 release version (and the code you
mentioned is in there). Nevertheless this sets it to a wrong number (I even
debugged it).
Funny thing is
root.getDeploymentManifest().getHeaders().get("AriesSubsystem-LastId").getValue()
returned "4" in my last debug session (after I had installed several
subsystems and restarted the bundle some times) so this does seem to change
sometimes. Unfortunately this is also wrong, the largest installed subsystem id
was 12 :-(

> aries subsystems will generate duplicate subsystem ids if the subsystem core
> bundle (or the container) is restarted.
> Reproduction is quite easy:
> 1. install a subsystem -> this will get subsystem id 1
> 2. stop the org.apache.aries.subsystem.core bundle (or the OSGi container)
> 3. start the org.apache.aries.subsystem.core bundle (or the OSGi container)
> -> the subsystem installed in step 1 is still there and has id 1
> 4. Install another subsystem (different from the first)
> -> This will also get Id 1
> I think the error is in line 150 of the
> org.apache.subsystems.core.internal.Subsystems class. There the static lastId
> counter of the SubsystemIdentifier class is set to 0 before actually
> populating the root subsystem.
> Maybe this should be set to the maximum id of the installed subsystems during
> or after the population of the root subsystem
