Tar task seems to be inserting "lone zero blocks"

           Summary: Tar task seems to be inserting "lone zero blocks"
           Product: Ant
           Version: 1.1
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Core tasks
        AssignedTo: dev@ant.apache.org
        ReportedBy: fgriffin@maine.rr.com


I noticed that the GNU tar 1.14 was producing warnings about "lone zero block
found" when unpacking certain packages from the web.  I've experienced this with
the 2.6.2 Xerces-J-bin, and also with the 4.0.0 JBoss source package.

I asked the JBoss people, and they said they created the archives with Ant
1.6.2, and I assume that Xerces is built with Ant.  So either
jboss-4.0.0-src.tar.bz2 or Xerces-J-bin.2.6.2.tar.gz can be considered a
reproducible case for this.

The warning out of GNU tar is just that.  I checked the source code, and the two
paths of execution are identical except for issuing the message.  But clearly
the GNU code thinks the block shouldn't be there.
