Hi,Thanks Julian and other contributors for fixing serveral UDF bugs of 1.5 version,.
However, These days I tried the version 1.6 , and find other UDF bugs, which will not happend in calcite 1.5 , may be regression bugs?
I have reported the bug details in : https://issues.apache.org/jira/browse/CALCITE-1075I tried to analyze the lastest source code and think the patch http://git-wip-us.apache.org/repos/asf/calcite/commit/d4bbf58d is not perfect.
