If 2 bundles are inter depended on each other , how these bundles dependencies will be resolved and started

In OSGi, when two bundles have circular dependencies (e.g., BundleA depends on BundleB, and BundleB depends on BundleA), the resolution depends on how the OSGi Service Component Runtime (SCR) manages service registration and injection. OSGi uses a dynamic service model, meaning that services can be published and consumed dynamically, helping to resolve circular dependencies to some extent.

Here’s how the circular dependency is handled:

1. Lazy Loading: OSGi services can be declared with lazy activation (Bundle-ActivationPolicy: lazy). This means a bundle is only activated when one of its services is actually used. This can help in managing circular dependencies because a service may not be activated until the dependent service is available.

2. Service References: Declarative Services (DS) allow bundles to declare references to other services using @3214626. The SCR manages these references and can dynamically bind services once they become available. If both services depend on each other, OSGi resolves this lazily, activating the services when needed.

I don't think that this will work at all, in the end the bundle dependencies need to form a directed tree, and not a graph with cycles.
