ChangeLogTask filterEntrySet throws NullPointerException

           Summary: ChangeLogTask filterEntrySet throws NullPointerException
           Product: Ant
           Version: 1.6.2
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Core tasks
        AssignedTo: dev@ant.apache.org
        ReportedBy: seanderickson@yahoo.com


When running the cvschangelog task like so:

<target name="cvs_changelog_today">
  <cvschangelog destfile="changelog.xml" dir="../src/" daysinpast="1" />
</target>

I get the output from ant, in verbose mode, with the exception:

background:

This task worked in the past but no longer works.  I am not sure if it quit
working with a java upgrade or an ant upgrade. 

I have verified this problem with Ant 1.5.3-1, 1.6.1, and 1.6.2

Here is my current Java version:
java -version
java version "1.4.2_03"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_03-b02)
Java HotSpot(TM) Client VM (build 1.4.2_03-b02, mixed mode)
