             Summary: TableEnvironment init fails with JDK9
                 Key: FLINK-19820
                 URL: https://issues.apache.org/jira/browse/FLINK-19820
             Project: Flink
          Issue Type: Bug
          Components: Table SQL / API
            Reporter: Timo Walther


I haven't verified the issue myself. But it seems that TableEnvironment cannot be properly initialized when using JDK9:

This might be fixed in later JDK versions but we should track the issue nevertheless. The full discussion can be found here:
