I do not think that CHAR and VARBINARY are compatible types. Try using
Types.VARCHAR instead.
In this case I think it is the client driver that is wrong. It is not
first example where it allows type conversions that are not according to
the spec. (Ref. https://issues.apache.org/jira/browse/DERBY-1501)
