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: [EMAIL PROTECTED]
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.)
