Activate, Deactivate, and Modified
The Declarative Service version 1.1 allows to specify the name for the
activate, deactivate and modified method (see the spec for more information).
The Activate, Deactivate, and Modified annotation can be used to mark a method
to be used for the specified purpose. However, as the DS specifies a method
search algorithm, there are rare cases where the marked method is not used (if
there is another method with the same name, but a different signature this
might happen).

This holds true for activate and deactivate. However, for modified, it doesn't
seem to work without explicitly declaring it so in the scr:component manifest.
Looking at impl/manager/ImmediateComponentManager.java, activate & deactivate
is not handled the same way as modified:
{code}
private boolean modify() {
...
// 1. no live update if there is no declared method
if ( getComponentMetadata().getModified() == null )
{
return false;
}
{code}
Thus, if not defined at all, it is not used. And that seems to be against the
spec.
