Hi there! I tried to use bundle:install/bundle:uninstall commands as you advised, but I had same errors:
``` ERROR | pipe-bundle:install -s file:/u00/test2/datasource-0.1.jar | container.BlueprintContainerImpl 440 | 35 - org.apache.aries.blueprint.core - 1.10.1 | Unable to start container for blueprint bundle org.example.dependent/0.1.0 org.osgi.service.blueprint.container.ComponentDefinitionException: Error when instantiating bean dependentService of class test.DependentService ... Caused by: java.lang.ClassCastException: test.Test cannot be cast to test.Test ``` The most interesting thing about this is that if I redeploy "dependent.jar" bundle - all is ok. I get result as expected. ``` 2020-04-06 11:58:51,326 | WARN | pipe-bundle:install -s file:/u00/test2/datasource-0.1.jar | test.DependentService 16 | 318 - org.example.dependent - 0.1.0 | Test{id='029bd5db-e67b-40bc-b9ca-f0f61cfc9708', name='Test1'} ``` But if I redeploy "domain.jar" too, I get an exception again: ``` ERROR | pipe-bundle:install -s file:/u00/test2/dependent-0.1.jar | container.BlueprintContainerImpl 440 | 35 - org.apache.aries.blueprint.core - 1.10.1 | Unable to start container for blueprint bundle org.example.dependent/0.1.0 org.osgi.service.blueprint.container.ComponentDefinitionException: Error when instantiating bean dependentService of class test.DependentService ``` It seems like karaf does not remove loaded classes after uninstall, so when I redeploy "domain bundle" karaf use new one classloader and "dependent.jar" bundle can't cast it. I don't understand why dependent.jar does not know about new domain.jar classloader and try to use outdated class -- Sent from: http://karaf.922171.n3.nabble.com/Karaf-Dev-f930721.html
