Yes - that works ok.

The issue that I have is that one "add" operation comes after my framework start and I am getting a concurrent exception when accessing a list built within the subsystem state. Here are the traces that I am getting :

23:54:32,026 INFO  [<myPkg>.TestSubsystemAdd] (Controller Boot Thread) Activating Test Subsystem
23:54:32,031 INFO  [<myPkg>.MyBootstrapService] (Controller Boot Thread) Test MyBootstrapService - created
23:54:32,031 INFO  [<myPkg>.MySubsystemState] (MSC service thread 1-3) MySubsystemState - started
23:54:32,031 INFO  [<myPkg>.TestAdd] (Controller Boot Thread) TestAdd --> execute Add                                  <<<<< this is OK
23:54:32,031 INFO  [<myPkg>.MyBootstrapService] (MSC service thread 1-10) Test MyBootstrapService - starting.
23:54:32,032 INFO  [<myPkg>.MyBootstrapService] (MSC service thread 1-10) Test MyBootstrapService - started in:0ms.
23:54:32,033 INFO  [<myPkg>.TestAdd] (Controller Boot Thread) TestModuleAdd --> execute Add                       <<<<< that comes out of sync

I do not understand why the last execute Add occurs AFTER the bootstrapservice started. And I am wondering how this is getting synchronized between the MSC service thread && the Controller Boot Thread. I do not get where I am messing it up ! 
I used the proper dependency when I add the bootstrap service towards the runtime subsystem state.

If you have an idea - it will be more than welcomed.

BR,
Dan S.
