>
> In certain situations a bundle, which has already been started gets its state
> changed back to RESOLVED.
> Consider the following situation: A thread T1 is starting a Bundle A while
> another thread T2 is starting a Bundle B depending on Bundle A. T2 resolves
> Bundle B and as T1 has not done it yet assumes to have to resolve Bundle A.
> Before T2 can resolve Bundle A, T1 resolves Bundle A itself and actually
> starts Bundle A at the end setting the state to ACTIVE. Then T2 finishes
> resolving and calls the ResolveListener to inform that Bundle A has been
> resolved, which causes the state of Bundle A to be set to RESOLVED.
> The consequence is that Bundle A has been started - BundleActivator called,
> STARTED event fired - and then its state is just set to RESOLVED and a
> RESOLVED event is fired. This is incorrect as (1) Bundle A has already
> started and before entering the RESOLVED state (again) it would have to be
> stopped and (2) getting A back into resolved state would cause STOPPING and
> STOPPED events to be fired and not a RESOLVED event.
> The fix would probably be to ignore the moduleResolved event for bundles,
> which are not in the INSTALLED state.
> Testing this issue is difficult as it heavily depends on timing and
> environmental issues, yet we have a setup, which produces the situation
> relatively often times.
