> 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
