> The DBOutputFormat adds a semi-colon to the end of the INSERT statement that 
> it uses to save fields to the database.  Semicolons are typically used in 
> command line programs but are not needed when using the JDBC API.  In this 
> case, the stray semi-colon breaks rewriteBatchedStatement support. See: 
> http://forums.mysql.com/read.php?39,271526,271526#msg-271526 for an example.
> In my use case, rewriteBatchedStatement is very useful because it increases 
> the speed of inserts and reduces memory consumption.
