[jira] [Commented] (KARAF-3748) Possible Constraint Violation when
installing activemq-blueprint feature
[ https://issues.apache.org/jira/browse/KARAF-3748?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14563203#comment-14563203 ]
Christian Schneider commented on KARAF-3748:
--------------------------------------------
Normally this case should not be a problem as both of the dependency chains end in the same bundle blueprint.core/1.4.3. (Please correct me if my assumption is wrong here).
I suspect that the problem is related to the fact that activemq-blueprint is a fragment to activemq-osgi.
The fact that the problem does not always occur could point to a timing or sequence problem.

> if you don't get the exception stop the container, delete data folder and try again.
