Crash in ntdll.dll due to JdbcOdbcConnection

Alan is correct, we do not officially support the bridge, from: 

Status of the JDBC-ODBC Bridge
The JDBC-ODBC Bridge should be considered a transitional solution. Sun Microsystems and DataDirect Technologies are working to make the Bridge more reliable and robust, but they do not consider it a supported product. With the development of pure Java JDBC drivers, the JDBC-ODBC Bridge should become unnecessary.

The above status has not changed in years (spanning multiple J2SE releases).  No new features have been added to the JDBC-ODBC Bridge in quite some time and there is really no plan to enhance it.

If you want to contribute a fix, I will look to include it when I have a cycle.
