             Summary: [Java Broker] MariaDB backed JDBC virtualhost truncates message content at 64K leading to Broker abnormal shutdown
                 Key: QPID-7982
                 URL: https://issues.apache.org/jira/browse/QPID-7982
             Project: Qpid
          Issue Type: Bug
          Components: Java Broker
            Reporter: Keith Wall


When using the Qpid Broker-J with a JDBC backed virtualhost using MariaDB, the database silently truncates message content at 64KB.  This means if the Broker needs to recover a message from disk (i.e. after a restart or after message content has been flowed to disk), it will fail to retrieve the expected number of message bytes and will fail as it tries to deliver the message to the consumer.  The failure also manifests if the message is viewed from Management.
