Hi all,

I've notice a strange java 7 behavior on windows when a "*" is used as argument:

Here is the test case, just printed out the args (pretty simple as you can see):

   public class TestStar
   {
      public static void main(String args[])
      {
        for (String _arg : args)
        {
          System.out.print(_arg + " ");
        }
        System.out.println();
      }
   }

On Unix, running ' java TestStar "*" ', both on jdk6 and jdk7 produce the expected output:

   $ echo $JAVA_HOME

   $ ./jdk1.6.0_26/bin/java -version
   java version "1.6.0_26"
   Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
   Java HotSpot(TM) Server VM (build 20.1-b02, mixed mode)
   $ ./jdk1.6.0_26/bin/java TestStar "*"
   *
   $ ./jdk1.7.0/bin/java -version
   java version "1.7.0"
   Java(TM) SE Runtime Environment (build 1.7.0-b147)
   Java HotSpot(TM) Server VM (build 21.0-b17, mixed mode)
   $ ./jdk1.7.0/bin/java TestStar "*"
   *
   $

On windows with jkd6, I've got the expected output:

   $ echo %JAVA_HOME%
   %JAVA_HOME%

   $ c:\Program Files\Java\jdk1.6.0_29\bin\java.exe -version
   'c:\Program' is not recognized as an internal or external command,
   operable program or batch file.

   $ "c:\Program Files\Java\jdk1.6.0_29\bin\java.exe" -version
   java version "1.6.0_29"
   Java(TM) SE Runtime Environment (build 1.6.0_29-b11)
   Java HotSpot(TM) Client VM (build 20.4-b02, mixed mode, sharing)

   $ "c:\Program Files\Java\jdk1.6.0_29\bin\java.exe" TestStar "*"
   *

   $

On windows with jkd7, the output **IS NOT** the expected one. It seems that the "*" is interpreted and list the directory

   $ "c:\Program Files\Java\jdk1.7.0_03\bin\java.exe" -version
   java version "1.7.0_03"
   Java(TM) SE Runtime Environment (build 1.7.0_03-b05)
   Java HotSpot(TM) Client VM (build 22.1-b02, mixed mode, sharing)

   $ "c:\Program Files\Java\jdk1.7.0_03\bin\java.exe" TestStar "*"
   TestStar.class

   $ "c:\Program Files\Java\jdk1.7.0_03\bin\java.exe" TestStar "\*"
   \$Recycle.Bin \a.bat \autoexec.bat \bar.emf \config.sys \dell
   \Documents and Set
   tings \FWLog.txt \Genius \hiberfil.sys
   \HP_CLJ_CP4020_CP4520_32bit_PCL6_HPDIU \H
   PDIU.log \MSOCache \pagefile.sys \partage \PerfLogs \Program Files
   \ProgramData
   \Recovery \System Volume Information \Users \Windows \xampp


Any info about this strange behavior?

Is it a bug?
Is there a workaround?

Thanks
Daniel
