> Over window codegen error when member code incorrectly used in method body
> --------------------------------------------------------------------------
>
> Key: FLINK-30499
> URL: https://issues.apache.org/jira/browse/FLINK-30499
> Project: Flink
> Issue Type: Bug
> Components: Table SQL / Planner
> Affects Versions: 1.16.0
> Reporter: Runkang He
> Assignee: Runkang He
> Priority: Blocker
>
> There is a bug in batch over window operator codegen, the comparator codegen
> logic is wrong that member code incorrectly used in method body. This causes
> over window code compile failed when operator initialization.
> The incorrect generated code for RangeBoundComparator is below, and the wrong
> place is *private static final java.util.TimeZone timeZone =
> java.util.TimeZone.getTimeZone("Asia/Shanghai");*
> which is a member statments that should be placed in class body, not method
> body.
