+1 looks good to me
> Include function class name in UserDefinedFunctionUtils exceptions
> ------------------------------------------------------------------
>
> Key: FLINK-6724
> URL: https://issues.apache.org/jira/browse/FLINK-6724
> Project: Flink
> Issue Type: Improvement
> Components: Table API & SQL
> Affects Versions: 1.4.0
> Reporter: Chesnay Schepler
> Assignee: Chesnay Schepler
> Priority: Trivial
>
> The {{UserDefinedFunctionUtils #checkForInstantiation}} checks whether a
> given function can be instantiated. If this is not the case it throws an
> exception like this:
> {code}
> org.apache.flink.table.api.ValidationException: Function class is not public.
> {code}
> It would be nice to include the class name in the exception.
