[Dev] Why is the activate method of an OSGi bundle called more than once?

Bhathiya Jayasekara Thu, 07 May 2015 06:31:12 -0700

Hi all,

I'm facing this situation where the activate method of an OSGi bundle[1] is
called many times. As you can see in below OSGi console output, the
service, that the bundle exposes, is also registered many times. What
should be the reason for this strange behavior?
