[jira] [Commented] (CALCITE-1770) Filters with Null fail with NPE

    [ https://issues.apache.org/jira/browse/CALCITE-1770?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15991468#comment-15991468 ] 

Julian Hyde commented on CALCITE-1770:
--------------------------------------

2 checkstyle violations, and I expect that maven-dependency-plugin will complain because we don't explicitly include commons-lang.

ObjectUtils.toString is a small method but its behavior is not obvious. I would just inline it and skip the use of commons-lang. What do you think.
