> While developing UDF and UDAF, users should be aware of association between Calcite RelType and Java Type. 
> Though Calcite validates SQL statement, there seems be the chance for UDAF to be called for unexpected parameter types, and "java.lang.IllegalArgumentException: argument type mismatch" is thrown.
> We can grab it and provide expected parameters and actual parameters so that users can investigate why.
