Xmmm...the answer is exactly in this paragraph...

If you need to wait for more than one service then you could use a
ServiceTracker with a Filter and a ServiceTrackerCustomizer to notify
your main thread but that is more complicated work. You could also use
a separate ServiceTracker for each service but that can get costly.
But I cannot figure out an elegant solution ... grrrr

Hello, OSGi community.
Here is my question. I have an OSGi service, that I want to initialize
it's facilities only when 3 other services are added to the framework.
I construct 3 service trackers (each one for every needed service).
How can I proceed after obtaining the knowledge that the 3 services
are ready? I am thinking of keeping a map maintained and at every add
and remove of service to check map's size and only if it is of size 3,
to proceed with the thread's execution. Is this practice very naive?
Is there something more obvious that I am missing?
Thank you!
My Best Regards,
Aggelos Mpimpoudis
