Guillaume Nodet commented on KARAF-4272: ---------------------------------------- Circular dependencies across a pre-requisite is definitely a problem. I don't see a simple cycle as a problem really, as what is declared is used as the desired end state, so having a cycle is fine because there's no ordering in that case. > Karaf freezes when a circular dependency is introduced where a feature > references itself over a chain of other features > ----------------------------------------------------------------------------------------------------------------------- > > Key: KARAF-4272 > URL: https://issues.apache.org/jira/browse/KARAF-4272 > Project: Karaf > Issue Type: Bug > Components: karaf-feature > Affects Versions: 4.0.4 > Reporter: Roland Hauser > Assignee: Guillaume Nodet > Fix For: 4.1.0 > > > Karaf freezes when a circular dependency is introduced where a features > references itself over a chain of other features > I did some experiments with circular dependencies where a feature references > itself indirectly over some other features. In this case it does not matter > if attribute {{prerequisite}} is set or not. After command {{feature:install > c-references-a}} Karaf freezes and must be restarted. > > I would expect, that the feature:install command fails with an error message > like this: > "Feature com.foo.bar could not be installed because a circular reference: > a-references-b > b-references-c > c-references-a" > You can checkout a project which helps to reproduce the case from > [https://github.com/SourcePond/reproduce-feature-circular-dependency.git] > (Maven-Modules c-references-a and c-references-a-prerequisite-true). Simply > install the root-project to have all necessary Maven dependencies. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
