["Richard S. Hall (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FELIX-2741?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13005274#comment-13005274 ] 

Richard S. Hall commented on FELIX-2741:
----------------------------------------

Guillaume, the new resolver is basically complete and committed. Could you try to see if you can re-create some of the issues you were experiencing previously for this error and others? You can build from trunk or grab the latest snapshots. Hopefully, this issue plus the ones you resolved for 3.0.9 are fixed in this version of the resolver, but if they aren't we should try to squash them for the coming framework 3.2.0 release.
