[Multiple Cloud Connections] Spurious component reactivations upon configuration change

[cdealti]

Multiple connections: updating a service (e.g. MqttDataTransport) of a connection has the effect to cause the unwanted reactivation of the next higher layer service (i.e. DataService) of the other connection(s). This in turn will cause the reactivation of all dependent components. This is not desired and not yet understood (Equinox bug?).

I wonder if we should consider upgrading Equinox at some point

[dwoodard1]

I think we should consider upgrading. I believe we are 5 versions behind at this point.

@MMaiero is this still present in Equinox 3.11?

[MMaiero]

@cdealti Unfortunately yes

[cdealti]

Then we should report this behavior to Equinox

[MMaiero]

I agree. Following what reported in kura-console.log. If I remember well, this is the same message that we got from the old osgi.

Are you sure this is an Equinox bug? What would the bug report towards Equinox look like?

[cdealti]

Closing as it is not causing any harm.
