AMQ Master/Slave Database Restart Results In Multiple Master Brokers

Issue

Using the following JDBC persistence adapter configuration with the default JDBC database locker

<jdbcPersistenceAdapter dataSource="#oracle-ds" lockKeepAlivePeriod="0" maxRows="200" cleanupPeriod="120000" />

it is possible to get two brokers running as master on the same JDBC store.
The key is to set lockKeepAlivePeriod="0", which disables keep alive.
