Hi,
No actually, it’s the expected behaviour. A mandatory property is required to
be set when the instance is created.
@Instantiate create an instance without any configuration, while you set a
property to be mandatory. The property is injected by the config admin after
the instance creation (as it’s a ManagedService configuration).
So you have 2 choices:
* either set the property to not mandatory and use the config admin to provide
a value after the instantiation
* use a ManagedServiceFactory configuration to instantiate the component (in
this case remove the @Instantiate)
