That seems to be a bug in Equinox. You may wish to file a bug report.
For giggles, try update 1 without stopping it first. The update operation
will automatically stop and restart the updated bundle.
Note: in order for import and exporting the package to work here, the
exported package in A' must be backwards compatible with the exported
package in A. This is because the remaining code in A' will be
implementing/using the interface from A.

Re: [equinox-dev] is this a service tracker bug?
Try adding:
Import-Package: bundlea.service
to the Bundle A manifest.

I just tried the suggestion above - but it blows up?

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.)
