This is exactly the problem - the system bundle is put in state ACTIVE before starting the bundles, which should be initially started, and the event is fired after starting the bundles. So when the state is ACTIVE we cannot be sure if this is before, or after the event is fired.

Right.

Hmm, well, Felix leaves it in STARTING while it reloads cached bundles...sounds like a bug in Equinox. ;-)

Yes, we could use FrameworkEvent.STARTED, but only if we are sure that

for it, is executed after the framework is started, then it will never
get the event. This happens in an Activator of a bundle â it may be
executed during the initial start of the framework, or after the
framework is started (for example on the first start of the bundle
after installing it). Therefore we need to be able to check the
framework state in one and the same way in both cases.

If you check the system bundle state in your activator, you can see if
it is active and if not, then register a framework listener to catch the
event, since the framework state can't change while you are in your
activator.

Yes, you should use the FrameworkEvent.STARTED event for this. You
should probably open a bug so we can investigate the current behavior
anyway to see if the comment is valid.

[equinox-dev] Starting the system bundle

Sent by:

Hello,

We are implementing logic which depends on the system bundle being put
in ACTIVE state after all bundles, which should be running, are
started. However, it turned out that actually the system bundle is put
in ACTIVE state just before the bundles are started. This is evident
from the method StartLevelManager.doSetStartLevel(â), which is called
from the EquinoxLauncher. There is a comment in the code, that putting
the bundle in ACTIVE state âshould be done just before firing the
STARTED event for the system bundleâ but is done earlier, because
âsome depend on the system bundle being in the ACTIVE state when they
are startingâ. Do you think it is possible to change the current
behavior and put the system bundle in ACTIVE state after the other
bundles are started, as it is in the OSGi spec?

Kind regards,
Lazar Kirchev_______________________________________________
