Subject [jira] [Commented] (OAK-5301) Possible null dereference in MapRecord
Date Wed, 14 Dec 2016 15:27:58 GMT

    [ https://issues.apache.org/jira/browse/OAK-5301?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15748622#comment-15748622

Michael Dürig commented on OAK-5301:

Fixing this will inevitably have an impact on the sort order. So we need to figure out what
was the initial intent of making {{MapRecord}} instances {{Comparable}}. As just removing
the implements clause doesn't break compilation I assume it is about order stability of {{MapRecord}}
instances when put into some containers. However, this leaves me to wonder why the class doesn't
implement {{equals()}} et. all., which would most likely as well be needed.

> {{MapEntry.compareTo()}} passes possibly {{null}} {{MapEntry.value}} to {{ComparisonChain.compare(Comparable,
Comparable)}}, which does not accept {{null}} values.
