Q: What is this SQL Server 2000 Exception? 
   [SQLServer JDBC Driver] Can't start a cloned connection while in manual transaction mode

A: This Exception is caused by the microsoft jdbc driver. It can be fixed
   by adding "SelectMethod=cursor" in the url, that is,
   bugzero.mssql.url=
   jdbc:microsoft:sqlserver://localhost:1433;SelectMethod=cursor;DatabaseName=bugzero_db

   (This should be the default setting)
