Hi,
We have serious problems with the Oracle JDBC connection "crashes" when
the setIncludeSynonyms is true and getting metadata. When
setIncludeSynonyms is false it works fine. The real context is a bought
product that uses setIncludeSynonyms = true..
Using ojdbc14_g.jar (10.2.0.2.0) and my test application is:
package test;
import java.sql.Connection;
import java.sql.DatabaseMetaData;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.util.Enumeration;
import oracle.jdbc.OracleConnection;
public class OracleTest {
public static void main(String[] args) {
try {
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
oracle.jdbc.driver.OracleLog.setTrace(true);
Enumeration enums = DriverManager.getDrivers();
while (enums.hasMoreElements()) {
System.out.println("Driver \"" +
enums.nextElement().getClass().getName() + "\" is loaded");
}
Connection conn =
DriverManager.getConnection("jdbc:oracle:thin:@ora.domain.net:1521:dbname",
"userid", "password");
System.out.println("Connection Class: " + conn.getClass().getName());
((OracleConnection)conn).setIncludeSynonyms(true);
DatabaseMetaData dbmd = conn.getMetaData();
ResultSet r = dbmd.getColumns(null, "MYSCHEMA", "MY_TABLE", "%");
while (r.next()) {
System.out.println("[Column name: "+ r.getString(4)+ "] [Data type:
" + r.getString(5)+ "] [Data type name: " + r.getString(5)+"]");
}
conn.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
This results in the following trace:
Driver "oracle.jdbc.driver.OracleDriver" is loaded
Driver "oracle.jdbc.driver.OracleDriver" is loaded

Why does this happen?
How can I solve this?
I would be very happy if someone could help me solve this.
