------------------------------------

             Summary: Support any kind of array in StringUtils.arrayAwareToString()
                 Key: FLINK-17489
                 URL: https://issues.apache.org/jira/browse/FLINK-17489
             Project: Flink
          Issue Type: Bug
          Components: API / Core
            Reporter: Timo Walther
            Assignee: Timo Walther


{{StringUtils.arrayAwareToString()}} is a very basic implementation for one-level nested arrays. However, such a prominent utility class should support all kinds of nested arrays. Both FLINK-16817 and FLINK-17175 tried to improve the implementation but the utility still does not support even {{int[][]}}.
