           Summary: dependset throws NullPointerException
           Product: Ant
           Version: 1.7.0
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Core
        AssignedTo: dev@ant.apache.org
        ReportedBy: joe.thompson@lmco.com


dependset throws a NullPointerException.  The failure appears to occur at the
point where DependSet.uptodate() sorts the list of sources, and gets the first
element of the list. (line 233 in DependSet.java). 
This works correctly in Version 1.6.5.
