FULL PRODUCT VERSION :
java version "1.5.0_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_01-b08)
Java HotSpot(TM) Client VM (build 1.5.0_01-b08, mixed mode, sharing)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Version 5.1.2600]

EXTRA RELEVANT SYSTEM CONFIGURATION :
Using Firebird SQL database 1.5.1 and Jaybird driver 1.5.5.

A DESCRIPTION OF THE PROBLEM :
The JdbcRowSetImpl(java.sql.Connection) constructor
internally throws (and then handles) a NullPointerException.
Although the NullPointerException is handled and not passed to the caller,
this indicates a problem in the JdbcRowSetImpl class and interferes with normal debugging practice (trapping all NullPointerExceptions).

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Just call the JdbcRowSetImpl(java.sql.Connection) constructor with a valid Connection parameter.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The JdbcRowSetImpl(java.sql.Connection) constructor should not generate and (need to) handle an internal NullPointerException.
ACTUAL -
If the debugger is set to trap all NullPointerExceptions, it will trap one inside the
JdbcRowSetImpl(java.sql.Connection) constructor.

ERROR MESSAGES/STACK TRACES THAT OCCUR :
No message and no exception propagated outside the constructor.
Execute the code below and set debugger to trap all NullPointerExceptions
(caught and uncaught). I have done this with Eclipse 3.1.0 (build 200412162000).

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
import java.sql.*;
import javax.sql.rowset.*;
import com.sun.rowset.*;

public class TestApp
{ public static void main(String args[])
   { Connection con; JdbcRowSet jdbcRs;
      try
      { Class.forName("org.firebirdsql.jdbc.FBDriver");
         con = DriverManager.getConnection(
                               "jdbc:firebirdsql:localhost:C:\\database.fdb",
                               "myName", "myPswd");
         jdbcRs = new JdbcRowSetImpl(con);
         // the line above internally throws and handles NullPointerException
      }
      catch(Exception exc) // NPE not caught, since handled inside constructor
      { System.out.println(exc.getMessage());
      }
   }
}
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Don't trap NullPointerExceptions inside this constructor.
