Re: [equinox-dev] is this a service tracker bug?
|
But you should not have to refresh. That is the whole point of importing
the package which is exported. So that A' can import it from A which is
where B imports it from.
I think the IllegalStateException is is a bug in Equinox.

I see - It's in an IllegalState until you refresh

Then when bundle A is updated to A', A' will import the package from A
which is where bundle B is importing it. So bundle B can "see" the service
from A' since it implements the interface from A. (This follows from Tom
Watson's explanation.)
