----------------------------------------------------------
Hmm, that is a problem, i think the message corresponding to the seqId from the
acks may not be in the store because it could already have been removed.
I think the brokerSeq should be set to the 'seq' in that case as a fallback.
On trunk there is a null check but brokerSeq defaults to 0, which means that
ids will be reused, in a failover message producer this could lead to
duplicates.
I think trunk needs to default the brokerSeq to the seq value returned from the
store.
fyi: the root problem is that the brokerSeq, incremented when a messages is
received cannot be used as the orderId/seqId in the store because they values
get out of sync when transactions are used, commits may be out of order w.r.t
to initial sends. For that reason, the next brokerSeq needs to be derived from
what is stored on a restart.
In the case that the value comes from what is acked and the message is no
longer available, using the value from the ack table as the new value makes
sense.

> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker
> Affects Versions: 5.3.2
> Environment: Linux hostname-removed 2.6.21.7-2.fc8xen #1 SMP Fri Feb
> 15 12:34:28 EST 2008 x86_64 x86_64 x86_64 GNU/Linux
> java version "1.6.0_21"
> Java(TM) SE Runtime Environment (build 1.6.0_21-b06)

> Reporter: josh anyan
> Priority: Critical
>
> Broker fails to restart due to a java.lang.NullPointerException. It looks
> like it has to do with the JDBC persistance adapter.
> I'm using:
> <journaledJDBC journalLogFiles="5"
> dataDirectory="${activemq.base}/activemq-data" dataSource="#mysql-ds"/>
> <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://myhostname.com/activemq?relaxAutoCommit=true"/>
> <property name="username" value="myusername"/>
> <property name="password" value="mypassword"/>
> <property name="poolPreparedStatements" value="true"/>
> I can solve this by emptying the table ACTIVEMQ_ACKS. It looks like there are
> some acks that exist for messages that aren't in the database.
