Java task classpath problems on JDK 1.2 and Windows 9x

           Summary: Java task classpath problems on JDK 1.2 and Windows 9x
           Product: Ant
           Version: 1.5.1
          Platform: PC
        OS/Version: Windows 9x
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Core tasks
        AssignedTo: ant-dev@jakarta.apache.org
        ReportedBy: edwin@woudt.nl


The java task does not work correctly if a classpath is specified and when it 
is executed on JDK 1.2 and Windows 9x. 

The following is the output:

     [java] Executing 'C:\JAVA\JDK12\JRE\bin\java.exe' with arguments:
     [java] '-classpath'
     
[java] 'C:\Devel\cryptix\projects\openpgp\build\classes;C:\Devel\cryptix\project
s\openpgp\lib\junit.jar;C:\Devel\cryptix\projects\openpgp\lib\cryptix-jce-
api.jar;C:\Devel\cryptix\projects\openpgp\lib\cryptix-jce-provider.jar'
     [java] 'cryptix.test.Test'
     [java] 'openpgp'
     [java]
     [java] The ' characters around the executable and arguments are
     [java] not part of the command.
     [java] java.lang.NoClassDefFoundError: 
C:\Devel\cryptix\projects\openpgp\lib\junit/jar
     [java] Exception in thread "main"

For this particular combination of JDK version and windows version, the 
batchfile antRun.bat is used to run the command. I added an echo statement to 
this batchfile to see the command line it generated. This was the result:

C:\JAVA\JDK12\JRE\bin\java.exe -classpath 
C:\Devel\cryptix\projects\openpgp\build\classes 
C:\Devel\cryptix\projects\openpgp\lib\junit.jar 
C:\Devel\cryptix\projects\openpgp\lib\cryptix-jce-api.jar 
C:\Devel\cryptix\projects\openpgp\lib\cryptix-jce-provider.jar 
cryptix.test.Test openpgp
     
As you can see the semicolons between the various elements of the classpath are 
missing and replaced by a space. This is because apparently windows treats 
semicolons on the command line as parameter separators.

The solution is to add quotes around the classpath when calling the batchfile. 
The attached patch should do the trick (unfortunately I could not get ant to 
build on my machine, thus was unable to test it).
