Weblogic 12c datasource is failing to connect with Proxy Authentication Set up

Hi All,

I am having a global datasource problem when I try to configure it for Proxy Authentication. 

I have created the following users :

CREATE USER proxytest IDENTIFIED BY proxytest;

/

GRANT CONNECT TO proxytest;

/

2. Create a user and give necessary permission

CREATE USER PROXYSVC IDENTIFIED BY test;

ALTER USER PROXYSVC GRANT CONNECT THROUGH proxytest

/

GRANT CREATE SESSION TO PROXYSVC

/

Now I create a generic datasource with driver set to oracle.jdbc.xa.client.OracleXADataSource;

"Oracle Proxy Session" is set to true.

"Use Database Credential" is set to "true"

Next I save the configuration and re-start the weblogic servers.  When the server comes up, I try to test the datasource connection, I get the following error
