This fix is in 11.2.0.4

Hi,

This is what I thought originally as it was 'reported' as fixed in Oracle Support but I tested it and the problem I was facing remains. This either means the the problem I am seeing is not exactly the same (and I am happy to be corrected if this is the case) or the core problem has not been fixed. To illustrate try compiling this and testing with JDBC 11.2.0.4 against an 11.2.0.4 database (ensuring the latest ojdbc6.jar is first in your CLASSPATH and adapt for your environment)

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

public class OracleDriverTest {

    /**
    * @param args the command line arguments
    * @throws java.sql.SQLException
    */
    public static void main(String[] args) throws SQLException {
        Connection connection = getConnection();
            Statement stmt;
            stmt = connection.createStatement();
            DatabaseMetaData dmd = connection.getMetaData();

            ResultSet rs = dmd.getColumns("", "SCOTT", "BONUS", "%"))

                while (rs.next()) {
                    System.out.println("Column: " + rs.getString("COLUMN_NAME"));
                    System.out.println("Data type: " + rs.getInt("DATA_TYPE"));
                    System.out.println("Size: " + rs.getInt("COLUMN_SIZE"));
                    System.out.println("Decimal digits: " + rs.getInt("DECIMAL_DIGITS"));
                }
    }

    public static Connection getConnection() throws SQLException {
        String username = "SCOTT";
        String password = "password";
        String thinConn = "jdbc:oracle:thin:@//localhost/ORCL";
        OracleDataSource ods;
        ods = new OracleDataSource();
        ods.setUser(username);
        ods.setPassword(password);
        ods.setURL(thinConn);
        Connection conn = ods.getConnection();
        DatabaseMetaData dbmd = conn.getMetaData();
        System.out.println("Database : " + dbmd.getDatabaseProductVersion());
        System.out.println("JDBC Driver : " +dbmd.getDriverVersion());
        conn.setAutoCommit(false);
        return conn;
    }

}

When I run this against my database I see this

$ /opt/jdk1.6.0_38/bin/java OracleDriverTest

Database : Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production

With the Partitioning, OLAP, Data Mining and Real Application Testing options

JDBC Driver : 11.2.0.4.0

Column: ENAME

Data type: 12

Size: 10

Decimal digits: 0

Column: JOB

Data type: 12

Size: 9

Decimal digits: 0

Column: SAL

Data type: 3

Size: 0

Decimal digits: -127

Column: COMM

Data type: 3

Size: 0

Decimal digits: -127

now compare the results when I use the oracle.jdbc.J2EE13Compliant=true argument

$ /opt/jdk1.6.0_38/bin/java -Doracle.jdbc.J2EE13Compliant=true OracleDriverTest

Database : Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production

Decimal digits: 0

Column: JOB

Column: SAL

Data type: 3

Size: 38

Decimal digits: 0

Column: COMM

This illustrates both the problem I am facing and a potential workaround/solution. The question is - is this the same bug or something different?
