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
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.
