[jira] [Created] (COLLECTIONS-516) NullPointerException in MapUtils.toProperties

Cyrille Artho created COLLECTIONS-516:
-----------------------------------------

             Summary: NullPointerException in MapUtils.toProperties
                 Key: COLLECTIONS-516
                 URL: https://issues.apache.org/jira/browse/COLLECTIONS-516
             Project: Commons Collections
          Issue Type: Bug
          Components: Collection
    Affects Versions: 4.0
         Environment: Mac OS 10.9, Java 6
            Reporter: Cyrille Artho
         Attachments: Report4.java

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.
