I have two web applications.
Both of yhem use oracle.ucp.UniversalConnectionPool.
When I deploy these applications on JBoss I get following exception:

java.sql.SQLException: Unable to start the Universal Connection Pool: java.sql.SQLException: Unable to start the Universal Connection Pool: oracle.ucp.UniversalConnectionPoolException: MBean exception occurred while registering or unregistering the MBean

Definition of data source bean:

<bean id="oracleDataSource" class="oracle.ucp.jdbc.PoolDataSourceFactory" factory-method="getPoolDataSource">
    <!-- hard coded properties -->
    <property name="connectionFactoryClassName" value="oracle.jdbc.pool.OracleDataSource" />
    <property name="validateConnectionOnBorrow" value="true" />
    <property name="connectionPoolName" value="ORACLE_CONNECTION_POOL" />
...
</bean>

Does anyone know how to fix this problem?
