[jira] Commented: (LUCENE-1246) Missing a null check in BooleanQuery.toString(String)

["Mark Miller (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LUCENE-1246?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12646400#action_12646400 ] 

Mark Miller commented on LUCENE-1246:
-------------------------------------

bq. Could one argue that maybe your queryParser/tokenizer shouldn't create null queries and add them to BooleanQuery clauses? 

I would argue that ; ) But I also would argue that a resilient toString() is a good idea anyway.

> Our queryParser/tokenizer in some situations creates null query and was added as a clause to Boolean query.
> When we try to log the query, NPE is thrown from log(booleanQuery).
> In BooleanQuery.toString(String), a simple null check is overlooked.
