Possible NullPointerException in Diagnositcs#doReport(PrintStream)

           Summary: Possible NullPointerException in
                    Diagnositcs#doReport(PrintStream)
           Product: Ant
           Version: 1.5.1
          Platform: Other
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Minor
          Priority: Other
         Component: Core
        AssignedTo: ant-dev@jakarta.apache.org
        ReportedBy: darin_swanson@oti.com


I am working with Ant 1.5.1 within Eclipse.
Within Eclipse it is possible to be using Ant without ANT_HOME set.

Diagnostics#listLibraries() throws a NullPointerException if ANT_HOME is not 
set.  The NPE occurs as the java.io.File#list call returns null.

I would propose that Diagnostics#listLibraries should handle this case. The 
comment claims the method will return null in error conditions but 
Diagnostics#doReportLibraries will not handle this return value.
