Journaled JDBC checkpoint fails with java.io.IOException: Already started.
--------------------------------------------------------------------------

                 Key: AMQ-1063
                 URL: https://issues.apache.org/activemq/browse/AMQ-1063
             Project: ActiveMQ
          Issue Type: Bug
          Components: Broker
         Environment: Windows XP Professional, JVM 1.5.0_09, MySQL 5.0.27
            Reporter: jk@penguinsfan.com
            Priority: Critical
             Fix For: 4.2.0


I am running trunk using JDBC against MySQL 5.0.27.  I am seeing the above mentioned IOException.
 Do not have specific instructions on how to reproduce at the current time, but I was using
durable subscriptions with the store durable cursor if that helps.  (I'll post if I find out
more information.)

      <persistenceAdapter>
   
      <journaledJDBC journalLogFiles="5" dataDirectory="../activemq-data" dataSource="#mysql-ds"/>

    </persistenceAdapter>

  <bean id="mysql-ds" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
    <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
    <property name="url" value="jdbc:mysql://localhost/activemq?relaxAutoCommit=true"/>
    <property name="username" value="*** OMITTED ***"/>
    <property name="password" value="*** OMITTED *** "/>
    <property name="poolPreparedStatements" value="true"/>
  </bean>
