invoke sql

I am a new comer to IDM and I am starting a little RnD in Sun Java Identity Manager for an up and coming project. I am creating a rule using Business Process Editor (BPE). I am trying the invoke ?lt;invoke name='sql' class='com.waveset.util.JdbcUtil'>?method with the Map constructor method. ../javadoc/com/waveset/util/JdbcUtil.html#sql(java.util.Map). All I am trying to do below is insert a row into a mysql DB with 4 bind parameters. I have successfully inserted a row with one bind parameter but when I add 2-4 bind parameters it always bombs on me and gives the output below. I can assure you all my values are set including arg 2. Any help would be appreciated.

Also I have turned logging on in MySQL and honestly it is no help because I can only see the prepare statement in the logs. I assume that the exception occurs before the execution.
