Dear all, We want to enhance the Java code style checking.
This is due to a discussion in [1]. In the discussion, we found the current style checking for Java code is not sufficient. So we want to enhace it in a series of "small" steps, in order to avoid having to change too many files at once. Currently, we have opened a JIRA [2] to track the problem of consecutive spaces between tokens. An initial PR [3] is prepared. Please see if it looks good to you. Thank you in advance. Best regards, Liya Fan [1] https://github.com/apache/arrow/pull/5861#discussion_r348917065 [2] https://issues.apache.org/jira/browse/ARROW-7429 [3] https://github.com/apache/arrow/pull/6060
