I had this same problem with MySQL 5.

There seems to be some sort of configuration issue with the file


There is a section for configuration of clustering

  |    <mbean code="org.jboss.messaging.core.jmx.MessagingPostOfficeService"
  |       name="jboss.messaging:service=PostOffice"
  |       xmbean-dd="xmdesc/MessagingPostOffice-xmbean.xml">
  |    ....
  |       <!-- This post office is non clustered. If you want a clustered post office then set to true -->
  |       <attribute name="Clustered">false</attribute>
  |    ....
  | </mbean>
What worked for me was deleting everything between
      <attribute name="Clustered">false</attribute> 

The file explicitly states that attributes after only matter if it is set to true and that they can safely be commented out otherwise.

Hope this helps someone - I certainly wasted enough time on this issue...
