I turned on some additional logging in our code to see what data is
being bound to each parameter in our UserType implementation.  It seems
the unspecified type is coming from a Date object bound with
PreparedStatement.setDate(int, java.sql.Date).  At least, this is the
first parameter that triggers the test.

A number of previous inserts contained "unknown" dates.  These were
bound with PreparedStatement.setNull(index, Types.DATE) before the test
was tripped by the PreparedStatement.setDate(index, date) in the stack
trace above.

I will run with the enhanced logging patch and upload results shortly.
