SimpleJdbcInsert Sometimes Fails with Java 1.6.0_18

This one is pretty awesome, I am getting an InvalidParameter exception for the SimpleJdbcInsert.executeAndReturnKey(). This only showed up when upgrading from Java 1.6.0_17 to 1.6.0_18. And the extra fun part is this does not occur on all calls to this method, only in isolated cases. It is totally awesome and I have no idea what is causing it....yet.

REVISION: 
Actually this was due to the fact I was passing a poorly formatted date string to the SimpleJdbcInsert object. I guess jdk1.6.0_18 is pickier than it's predecessor.
