EDIT: updated this question with latest information...
I'm having issues running back-to-back "features:uninstall" commands for dependent features. OSGi responds back with "State change in progress...", but by accepting other requests, we run into issues.
Strangely, this results in successful feature uninstalls, but unsuccessful bundle uninstalls. We are addressing this by trying to order uninstall requests appropriately and adding a delay between steps, but I'm hoping for a more robust solution.
As suggested, I also tried adding "osgi:refresh" in between steps...same behavior. Is there another way to detect that "Refresh Packages" is still running to delay subsequent requests, etc?
Here are the details...
karaf@root> features:uninstall PolicyUtil
karaf@root> features:uninstall Policy1
karaf@root> features:uninstall Policy2
State change in progress for bundle "file:/policy2.jar" by thread "Refresh Packages".
karaf@root> features:uninstall Policy3
State change in progress for bundle "file:/policy3.jar" by thread "Refresh Packages".
karaf@root> features:uninstall Policy4
karaf@root> features:uninstall Enabler1
State change in progress for bundle "file:/enabler1.jar" by thread "Refresh Packages".
karaf@root> features:uninstall Enabler2
State change in progress for bundle "file:/enabler2.jar" by thread "Refresh Packages".
afterwards...we end up with features uninstalled (correct), but some bundles still installed (incorrect)
osgi:list

Alright, I've been digging into this and I think I understand the issue and the options...thanks for the responses.
When "features:uninstall [name]" is executed, it calls bundle.uninstall(), then refreshPackages() for each bundle in the features. Then, after all bundles are uninstalled, it calls refreshPackages() for all bundles. The issue is that refreshPackages() is asynchronous (per the OSGi spec) and leaves bundles in a resolving state. Subsequent requests to uninstall resolving features/bundles fail to complete as expected.
If there is sufficient delay in between uninstalls or if a later uninstall is executed (after the refreshPackages() has completed)...everything works as expected.
