Sample code to demo the problem with passing a null to a method also results in a NullPointerException within EoD RI
I could not get a successful execution of a method such as

@Update("insert into foo("?1")
void addFoo(String x)


if i changed the method to return an int, it worked fine
if i have an EoD Update such as

@Update("insert into foo values(?1, ?2)")
 int insertRow(String x, String y)


if i invoke insertRow("x", null)

I get an Exception processing the arguments (the table supports nulls for the column but
the Exception is before it gets to the backend)
I cannot have more then 9 parameters in my eod query if i have ?10, it will fail to parse the query correctly
