             Summary: Using activemq-web-console feature in Apache Karaf can 
result in ClassCastException
                 Key: AMQ-5501
                 URL: https://issues.apache.org/jira/browse/AMQ-5501
             Project: ActiveMQ
          Issue Type: Bug
          Components: webconsole
    Affects Versions: 5.10.0
            Reporter: Achim Finke


Depending on the installation order of features activemq related features using 
the activemq-web-console feature in Apache Karaf can result in a 
ClassCastException.

The reason for this seems to be the existence of multiple versions of 
javax.jms. The activemq features installs amongst others the 
geronimo-jms_1.1_spec-1.1.1 bundle. In addition the activemq-web-console WAB 
embedds geronimo-jms_1.1_spec-1.1.1.

Installing the activemq-web-console feature before the activemq feature results 
for me in a later ClassCastException.

Check the following [demo 
project|https://github.com/achim86/issues/tree/master/activemq-playground] to 
reproduce the error.

When analyzing the issue I noticed that the activemq-web-console WAB exports 
many org.apache.activemq.* packages. Are there any reasons for this?
