I have the same error with the configuration:

  <persistenceAdapter>
       <journaledJDBC journalLogFiles="5"
dataDirectory="${activemq.base}/activ
emq-data"  dataSource="#mysql-ds"/>
   </persistenceAdapter>

and

<persistenceAdapter>
                       <journaledJDBC  dataSource="#mysql-ds"
useDatabaseLock="
false"/>
</persistenceAdapter>.


with mysql-ds bean:
<bean id="mysql-ds" class="org.apache.commons.dbcp.BasicDataSource"
destroy-me
thod="close">
   <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
   <property name="url"
value="jdbc:mysql://***.***.***.***/activemq?relaxAutoCo
mmit=true"/>
   <property name="username" value="*****"/>
   <property name="password" value="******"/>
   <property name="poolPreparedStatements" value="true"/>
    <property name="initialSize" value="10" />
    <property name="maxActive" value="64" />
               <property name="maxIdle" value="2" />
               <property name="maxWait" value="15000" />
 </bean>

Can anyone help  me solve this issue?

Thanks in advance.

Hi Nuno,

could you raise a jira for this so we can track it  ? - see
