> Diff the file, we can find TextElement is used here where ClosureCleanerLevel is is used as a memeber of Serializable ExecutionConfig.

> The simplest way to verify the problem is running code as followings in flink 1.13.5 and 1.14.x, the exception is reproduced in 1.14.x . And the diff between 1.13.5 and 1.14.x is only lates commit
