Hi,
I need your help. I am porting our project to Nitrogen and have serious
problems with Karaf 4 features. There is something that I don't understand
there.
On clean Karaf, I first install ODL feature odl-mdsal-apidocs:
>feature:install odl-mdsal-apidocs
>list | grep -i -v active
START LEVEL 100 , List Threshold: 50
ID | State | Lvl | Version | Name
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
31 | Resolved | 80 | 4.0.9 | Apache Karaf ::
Diagnostic :: Boot
183 | Resolved | 80 | 0.7.0 |
config-persister-directory-xml-adapter, Hosts: 185
184 | Resolved | 80 | 0.7.0 |
config-persister-file-xml-adapter, Hosts: 185
No problems. Then I want to install a third party bundle
org.apache.mina/mina-core/2.0.9 . If I install it as a bundle, I still don't
see any problem.
>bundle:install -s mvn:org.apache.mina/mina-core/2.0.9
>list | grep -i -v active
START LEVEL 100 , List Threshold: 50
ID | State | Lvl | Version | Name

config-persister-directory-xml-adapter, Hosts: 185
184 | Resolved | 80 | 0.7.0 |
config-persister-file-xml-adapter, Hosts: 185
However, if I wrap it in a feature, I get absolutely different behavior.
>feature:install -v my-feature

The "mina" bundle itself is not very important. The same behavior I observed
with some other bundles. I don't understand why Karaf restarts already
installed bundles simply because I added one more. Why is it important that the
bundle is wrapped in a feature? Can I disable such behavior?
Thanks,
Yevgeny
