Subject Re: What kind of things would prevent a set of bundles from going Active?
Date Sat, 30 Sep 2017 05:49:03 GMT

When a bundle is resolved, it means that the constraints resolution is OK. 
Basically, Import packages & requirements are satisfied.

So, a bundle stays in Installed state if it can go to Resolved due to a 
unsatisfied resolution constraint (for instance an imported package is not present).

When a bundle is in Resolved state, it's possible to start it. Basically it 
means calling the start method of the activator. If the start method works and 
didn't throw an exception, then, the bundle becomes active.

In the case of blueprint, the activator is managed by blueprint. Grace-Period 
means that blueprint is looking for a dependency service at startup and it 
doesn't find it. So, he's waiting for the service.

bundle:diag or log gives you detail about the service not present.

of the application-specific bundles are "Installed", or even "Grace Period".
