Empty value attribute for <arg> behaves differently on Windows and Unix





------- Additional Comments From peter.reilly@corvil.com  2003-11-04 12:36 -------
I have tested this on windows.
I can only see this behaviour if one does:
<java classname="MyClass" classpath="${myclasspath}" fork="yes">
  <arg value="1"/>
  <arg value=""/>
  <arg value="3"/>
</java>

The reason for this is the fact that Runtime.exec(String[] ...) is
platform specific and for windows J2SE (at least up to 1.4.1) uses

CreateProcess(0, commandline, ....)

Where the second parameter is a string containing the commandline
including all the arguements.

In the conversion to a string, the second arguement gets lost.

The code for the conversion is in the constructor of the class
W32Process (available under sun's community source license)
looking at the code and at 
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dllproc/base/createprocess.asp
I cannot see a way to make this work correctly.
I would be inclined to set this to WONTFIX as in CANTFIX
