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
