Re: [p2-dev] services in p2

[John Arthorne <John_Arthorne@xxxxxxxxxx>]

We currently rely on the exemplary setup
bundle to register all the services in the appropriate order. I believe
in other headless apps we either use exemplary setup, or manually register
the services we need in the correct order. Yes, this is a bit gross, and
there has been lots of discussion about how to fix this. See for example
https://bugs.eclipse.org/bugs/show_bug.cgi?id=225250.

I don't suggest messing with bundle
start levels to work around it.

Subject	[p2-dev] services in p2

I was running the publisher (bundles and features) to
test some things out, and I started to receive errors in my OSGi console.
After hacking around a bit, I realized what was going
on.

In metadata repository (CacheManager), we are trying to
get IProvisioningEventBus service.  However, this service was not
actually being registered until the Abstract publisher application runs.
 Because these two bundles (Metadata repo and the publisher) are both
started at the default run level, it is anyones guess which one will run
first.

Should we be considering DS for stuff like this, or should
I just start these bundles at different start levels in my launch configurations?

Cheers,
Ian
