["Netlancer (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AMQ-5105?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13936445#comment-13936445 ] 

Netlancer commented on AMQ-5105:
--------------------------------

Current workaround is to 
Removing pax-url-aether-1.5.2.jar and disabling logQuery in activemq.conf 

   <!-- Allows accessing the server log -->
    <!--bean id="logQuery" class="org.fusesource.insight.log.log4j.Log4jLogQuery"
          lazy-init="false" scope="singleton"
          init-method="start" destroy-method="stop">
    </bean-->

> The problem seems to be because of multiple jars having the same classes

> pax-url-aether-1.5.2.jar
> The class present in pax-url-aether-1.5.2.jar gets loaded causing level db to fail.
