Description

From time to time you get the following exception when installing activemq-blueprint feature.

org.osgi.service.resolver.ResolutionException: Uses constraint violation. Unable to resolve resource org.apache.activemq.activemq-blueprint [org.apache.activemq.activemq-blueprint/5.11.1] because it is exposed to package 'org.apache.aries.blueprint' from resources org.apache.aries.blueprint.core [org.apache.aries.blueprint.core/1.4.3] and org.apache.aries.blueprint.core [org.apache.aries.blueprint.core/1.4.3] via two dependency chains.

The behaviour is not predictable. Installation worked x times, afterwards installation failed y times so you may need some trys to reproduce.

To reproduce execute:

feature:repo-add activemq 5.11.1
feature:install activemq-blueprint

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