Resolver does not clean up properly on a failed recursive attempt to resolve
----------------------------------------------------------------------------
Key: FELIX-978
URL: https://issues.apache.org/jira/browse/FELIX-978
Project: Felix
Issue Type: Bug
Components: Framework, Specification compliance
Affects Versions: felix-1.4.1
Reporter: Richard S. Hall
Assignee: Richard S. Hall
Fix For: felix-1.6.0
When the resolver is calculating the set of potential candidates for module
being resolved, it uses a map to store the potential candidates associated with
each module that needs to be resolved. It also uses this map to detect cycles.
In the case there are no potential candidates to resolve a dependency, the
attempt to populate candidates for the given module fails. However, the failed
module is not removed from the candidates map. The result is in certain
situations, the resolver may end up wiring to the failed module since it still
has candidates in the candidate map. This typically can only happen if there
are multiple dependencies on the failed module with at least one of them being
optional.
