ERROR when trying to configure Oracle AQ with WSO2 Micro Integrator

Question

I'm trying to configure Oracle AQ with WSO2 Micro Integrator 4.2.0. I created oracle Queue and I was able to send and messages there. Howver when I tried to configure it with WSO2 MI and trying to send message using Proxy service I'm getting the below error.

ERROR {JMSConnectionFactory} - Error looking up the JMS destination with name Queues/Q of type queue javax.naming.NamingException: Cannot resolve name:Queues/Q [Root exception is oracle.jms.AQjmsException: ORA-28009: connection as SYS should be as SYSDBA or SYSOPER

Caused by: oracle.jms.AQjmsException: ORA-28009: connection as SYS should be as SYSDBA or SYSOPER

I have already placed required drivers also. And tried to provide "sys as SYSDBA" in the naming security principal.

Below is the address I used in the proxy service.

<address uri="jms:/Queues/Q?transport.jms.ConnectionFactoryJNDIName=QueueConnectionFactory&amp;java.naming.factory.initial=oracle.jms.AQjmsInitialContextFactory&amp;java.naming.provider.url=jdbc:oracle:thin:@localhost:1521/xe&amp;transport.jms.DestinationType=queue&amp;java.naming.security.principal=sys&amp;java.naming.security.credentials=oracle&amp;db_url=jdbc:oracle:thin:@localhost:1521/xe"/>

Any inputs, how to resolve this issue?
