Mark,

I opened https://bugs.eclipse.org/bugs/show_bug.cgi?id=216648 for you. I tried to CC you to the bug but I noticed you did not seem to have a bugzilla e-mail, unless you use a different e-mail for bugzilla than the one you use to post to equinox-dev.

:( I'll file a report - one other solution pointed out was to seperate interface (api) from the impl and the client.

So I guess I should create A, B, and C

(A)pi, Impl-(B)undle, and (C)lient

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.

Try adding:

Import-Package: bundlea.service

to the Bundle A manifest.

Then when bundle A is updated to A', A' will import the package from A

from A' since it implements the interface from A. (This follows from Tom
Watson's explanation.)
