Java 2 Platform SE v1.3 Specification reads:

public Process exec(String command,String[] envp,File dir) throws IOException

------ cut -----

Parameters:
            command - a specified system command.
            envp - array of strings, each element of which has environment variable settings in format
            name=value.
            dir - the working directory of the subprocess, or null if the subprocess should inherit the working
            directory of the current process.

-----------------------------------------------------

The following program tests correct work of java.lang.Runtime.exec(String cmd, String [] envp, File path)
method. The test executes /bin/pwd with root working directory.
The expected output of /bin/pwd is "/" but under jdk1.3.0beta for linux it produces
instead of "/" the value of java machine working directory.
This means that java machine didn't change working directory during
Runtime.exec method invocation.

The test passes on jdk1.3.0Z for solaris.

--------------------------------- test.java ---------
import java.io.*;

public class test {
    public static void main(String [] args)
    {
        try
        {
            Process p;
            String cmd="/bin/pwd";
            File f=new File("/");

            p = Runtime.getRuntime().exec(cmd, null, f);

            BufferedReader in = new BufferedReader
                (new InputStreamReader(p.getInputStream()));

            String s = in.readLine();
            if(s.compareTo("/")!=0)
                  System.out.println("Error: directory differes from expected:"+s);
            else System.out.println("Passed.");
        }
        catch(Exception e)
        {
            System.out.println(e);
        }
    }
}
----------------------------- output ----------------------------------
