Description

To reproduce:

1. clone this project and build it with maven:

   mkdir -p ~/git
   cd ~/git
   git clone https://github.com/steinarb/liquibase-karaf-feature/
   cd liquibase-karaf-feature
   mvn clean install
   

2. start karaf and give the following commands to the karaf console:

   feature:repo-add mvn:no.priv.bang.karaf/liquibase-core-karaf/LATEST/xml/features
   feature:install liquibase-core
   

3. uninstall the feature

   feature:uninstall liquibase-core
   

Karaf will now output the following and hang:

karaf@root()> feature:install liquibase-core
karaf@root()> feature:uninstall liquibase-core
karaf@root()>
java.lang.IllegalStateException: No inital startlevel yet
        at org.apache.felix.framework.FrameworkStartLevelImpl.setStartLevel(FrameworkStartLevelImpl.java:131)
        at org.apache.karaf.main.Main.setStartLevel(Main.java:605)
        at org.apache.karaf.main.Main$KarafLockCallback.lockAquired(Main.java:711)

        at org.apache.karaf.main.Main$3.run(Main.java:369)

On karaf 4.0.7 the crash on uninstall doesn't happen.

If the liquibase-slf4j fragment bundle is removed from the liquibase-core feature, the crash on uninstall doesn't happen.
