Issue Type: Bug
Affects Versions: 1.6.0
Reporter: Wei Hu

UDF Error In Calcite 1.6, may be Regression bugs?
schema：Table:hr, A String， B String， C String， D Timestamp
UDF： FUNC（Timestamp D） returns a timestamp value
there a several regression bugs. 1.5 is ok, but 1.6 will throw exception:
1. UDF in Group_by clause,
sql：select min(m0), max(m0) from (select FUNC(D) as d1, COUNT(A) as m0 from
\"hr\" group by FUNC(D))
Error Stack：
Caused by: java.lang.ClassCastException: java.sql.Timestamp cannot be cast to
java.lang.Long
