cvschangelog crashes with NullPointerException

           Summary: cvschangelog crashes with NullPointerException
           Product: Ant
           Version: 1.5.3
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Optional Tasks
        AssignedTo: dev@ant.apache.org
        ReportedBy: benno.loeffler@gmx.de


Hi,
I try to make cvschangelog running and face a strange problem that nobody else 
seems to have: cvschangelog crashes with a NullPointerException.
My task looks like:
<target name="cvs.changelog">
        <cvschangelog 
               dir="somedir" 
               destfile="changelog.xml"/>
</target>

The error that I get (with ant 1.5.3 and 1.6.1) looks like (full trace 
attached at end of file):
java.lang.NullPointerException
        at java.util.Calendar.setTime(Calendar.java:902)

Using  plain cvs works:
cvs log -N -d "11 Aug 2004<31 Aug 2004" somedir
outputs a correct result (for a full trace, see end of file):
cvs log: Logging somedir
...
...
So the cvs configuration seems to be ok.
I tried to add the daysinpast="7" option to only report for one week in the 
past but it still crashes with a slightly different problem: a 
NullPointerException in java.util.Date. 
If I specify a daysinpast="1" so that no entries are generated at all (because 
there was no change yesterday...), cvschangelog task runs and generates an 
empty report successfully.
Could this be caused by an incompatible cvs.exe - optional.jar combination? Or 
may the cvs-server version (1.12.7) be incompatible with ant 1.5.3 
optional.jar? I also tried combinations with ant 1.6.1 optional.jar ... but 
did result in the same error.
The cvs.exe that is in my path belongs to wincvs1.3 and reports version 
2.0.41a.
I'm working on winxp sp2.

Any ideas what the problem could be? I hardly can't believe that it is a bug 
in ant, but I just don’t find any solution.

Best Regards
Benno
