EXTRA RELEVANT SYSTEM CONFIGURATION :

A DESCRIPTION OF THE PROBLEM :
I am working on an enterprise web application, which is used by many users. In this , I connect to oracle db to get a STRUCT object consists of two fields. In execution, one user or more users are getting other user STRUCT object details.
Example If user A, B, C are accessing DB. Acutally A should get "a" STRUCT object. B should get "b" object. And C should get "c" object. But all A, B and C are getting "a" STRUCT object only.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1) Configure your JVM to have 128 MB heap space.
2) Create a simple web application, which should get a STRUCT object from Oracle Database.
3) Access that application with 100 number of users at a time to get STRUCT object.


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
As mentioned in the description example, while accessing DB, A should bet "a" STRUCT object, B should get "b" object and C should get "c" object, where application is accessed by 100+ users.
ACTUAL -
As mentioned in the description example, while accessing DB, A , B, C are getting same object "a", which is not correct object for B and C, where application is accessed by 100+ users.

ERROR MESSAGES/STACK TRACES THAT OCCUR :
There are no error logs for this.

REPRODUCIBILITY :
This bug can be reproduced occasionally.

---------- BEGIN SOURCE ----------
call_GETSERVICE_Statement = connection.prepareCall(
                    "{call " + GETSERVICE_PROCEDURE_FOR_USER + "(?,?,?)}");
            call_GETSERVICE_Statement.setString(1, so_ServiceId);
            call_GETSERVICE_Statement.registerOutParameter(2,
                                                           OracleTypes.STRUCT,
                                                           DB_OBJECT_SERVICE);
            call_GETSERVICE_Statement.registerOutParameter(3,
                                                           OracleTypes.STRUCT,
                                                           DB_OBJECT_CALLSTATUS);

            call_GETSERVICE_Statement.execute();

            STRUCT callstatusSTRUCT = (STRUCT) call_GETSERVICE_Statement.getObject(
                    GETSERVICE_OBJ_CALLSTATUS);
            Object[] callstatusAttribs = callstatusSTRUCT.getAttributes();



//callstatusAttribs are different for different users.But getting same STRUCT object for all users.
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
I am manually updating user details in application, which is too hectic.
