Subject [jira] [Commented] (COLLECTIONS-516) NullPointerException in MapUtils.toProperties
Date Thu, 10 Apr 2014 23:09:16 GMT

Cyrille Artho commented on COLLECTIONS-516:
-------------------------------------------

Thank you for commenting on this. Based on your opinion, I agree that a minor change in the
javadoc comment is probably best. Maybe:
"Entries in the map must be non-null. If a null reference is given for the map, this method
will return an empty properties object."

> calling MapUtils.toProperties with a map having null entries results in a NullPointerException.
In this case the Map has only entry <null, null>.
> However, javadoc states "A null input will return an empty
> properties object." so (1) this should be clarified as it would
> only apply to the map reference itself, not its contents, or (2)
> an empty property object should be generated for null entries in
> the map as well.
