------------------------------------

             Summary: Duplicate subsystem ids after restart of subsystem.core
                 Key: ARIES-1109
                 URL: https://issues.apache.org/jira/browse/ARIES-1109
             Project: Aries
          Issue Type: Bug
          Components: Subsystem
            Reporter: Stephan Siano


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
