viasyn commented on KARAF-3787:
-------------------------------
Thank you for you kindest replies.
So, maybe it's possible to introduce some debug features? Maybe just check that
bundle classloader is not empty before bundle start and print warning in log?

> I have a simple bundle.
> I installed and started it and it works.
> When I rebuild it with some changes, then reinstall it:
> {code}
> uninstall com.demo.*
> install
> http://localhost:8081/nexus/content/repositories/obr-local/com/demo/discovery-dns_2.11/1.0-SNAPSHOT/discovery-dns_2.11-1.0-SNAPSHOT.jar
> {code}
> It reinstalls successfully, but when I'm checking for new behaviour I found
> the old one.
> Looks like classes was not reloaded.
> This problem is really bothers me, because I'm trying to implement logic
> dynamically reconfiguring server roles.
> Here is my bundle's manifest. Note that I modifying class in private-package
> (but for export-package problem remains)
