java.text.ParseException: Unparseable date

I can use Maven to get the source code from ClearCase and build file. And I want to use the changelog plugin and my goal is "-e clean -Dmaven.test.skip=true compile package changelog:changelog"

But I got the following error. I'm not sure this is changelog's error or clearcase plugin's. Is there any suggestion for it?

btw, I found http://jira.codehaus.org/browse/MCHANGELOG-115, but I'm not sure is it the same problem because it's environment is subversion.
