This is exactly the case. Our Declarative Services implementation
maintains a single background thread which is responsible for binding
references and activating components.
So, yes, here you generally will not get a bind or unbind call while in
the activate method.
I chose this implementation to
Yes, sorry with "felix " I was actually meaning "Felix Declarative
Services".

I am not sure if this has anything to do with Felix per se, it sounds
like more of a feature of the SCR implementation. Perhaps SCR queues its
work, in which case, the activate would be processed before the bind.

But as in the scenario of the experiment felix is actually waiting with
enabling (and injecting) the second component till the first one (the
one with the Thread.sleep) finished activating. Why does felix wait half
a minute if not forced by specification?

Indeed, this is NOT guaranteed.
What you will find in small-scale testing is that it's actually quite
hard to force the concurrency to happen, because you can't get the
thread scheduler to switch contexts when you want it to. But the bugs
are only hiding, and are likely to appear when the componen
experimenting with felix I found that dynamic dependencies are not
injected while the acivate method is being executed.
The experiment code

* @scr.reference name="component" cardinality="0..n" policy="dynamic"
*interface="java.lang.Object" target="(testing=
It depends. If your component uses the "static policy" then the
binds/unbinds will not happen concurrently with the
activate/deactivate methods.
However, if you use "dynamic" policy then they certainly can happen
concurrently and you need to write your component to be thread-safe.

I guess a simple question: is it guaranteed that the
activate,deactivate, the bind- and unbind methods of a component are not
called synchronously?
