viasyn updated KARAF-3787:
--------------------------
Attachment: karaf_class_unloading.png
I tried to look for Karaf through JVisualVM.
Looks like Karaf don't unloads classes when corresponding bundles uninstalled.
Please look at screenshot I've attached: loaded classes count remains unchanged
even when I removed all the bundles installed:
{code}
karaf@root()> uninstall 58 60 65 68 69 70 71 72 73
karaf@root()> list
START LEVEL 100 , List Threshold: 50

>
> 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)
