Hi Rob, thanks for the suggestion. I have tried the KahaDB adaptor, and it
does endeed change the behaviour but I am still getting the same error
message every other time I restart. The major difference is that now,
despite the error message, everything seems to work :)
I forgot to mention something important earlier on, that may be important:
I am using the ajax listener. The configuration that I have in web.html is
<context-param>
<param-name>org.apache.activemq.brokerURL</param-name>
<param-value>vm://BrokerA?create=false</param-value>
</context-param>
<context-param>
<param-name>org.apache.activemq.embeddedBroker</param-name>
<param-value>true</param-value>
</context-param>
<servlet>
<servlet-name>AjaxServlet</servlet-name>
<servlet-class>org.apache.activemq.web.AjaxServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>AjaxServlet</servlet-name>
<url-pattern>/amq/*</url-pattern>
</servlet-mapping>
May be it has something to do with this?
