Please help me to confirm this error on Oracle 11.2.0.4:

set serveroutput on;
call dbms_java.set_output(50);

CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED "CREATE_BLOB_TEST" AS

package createBlobTest;

import java.sql.*;
import oracle.jdbc.*;
import oracle.jdbc.pool.*;

class CreateBlobTest {

                public static  Blob test() throws Exception {
                                Connection connection;
                                OracleDataSource ds;
                                String connectUrl = "jdbc:default:connection:";

                                ds = new oracle.jdbc.pool.OracleDataSource();
                                ds.setURL(connectUrl);
                                connection = (OracleConnection) ds.getConnection();

                                DatabaseMetaData dbmd = connection.getMetaData();
                                System.out.println("Database Version: " + dbmd.getDatabaseProductVersion() );
                                System.out.println("Driver Version: " + dbmd.getDriverVersion() );

                                return  connection.createBlob();
                }
}
/

CREATE OR REPLACE FUNCTION createblobtest RETURN BLOB AS
    LANGUAGE JAVA
    NAME 'createBlobTest.CreateBlobTest.test() return java.sql.Blob' ;

BEGIN
    dbms_output.put_line (dbms_lob.getlength (createblobtest ()));

Output on Oracle 12.2.0.1:
Database Version: Oracle Database 12c Enterprise Edition Release 12.2.0.1.0 - 64bit Production
Driver Version: 12.2.0.1.0

I'm hoping that one would be able to fix/update the database's JDBC driver on 11.2.0.

In 11.2, with jvm 1.5, neither (embedded) java.sql.Connection nor oracle.jdbc.OracleConnection class implements the CreateBlob method (it is inherited from java.sql.Connection in 12c and was introduced in jvm 1.6) and, unfortunately, I think you cannot upgrade the database jvm.
I'm afraid there is nothing to do but upgrade Oracle itself.

Thank you Michel Smile
Up to now Oracle Support is unable (or unwilling) to just execute the code and confirm the problem on 11g.
