Runtime.exec(String[]) does not correctly handle a command argument that
contains a space and ends with a backslash.

-- The following program demonstrates the problem

import java.io.*;
import java.util.*;

public class Cmd {

    private static String getJavaCommand() {
        String javaHome = System.getProperty("java.home");
        if (javaHome != null && javaHome.length() > 0)
            return (javaHome
                    + File.separatorChar + "bin"
                    + File.separatorChar + "java");
        else
            return "java";
    }

    public static void main(String[] args) throws Exception {

        if (args.length > 0) {
            System.err.println("child: " + args[0]);
            return;
        }

        String[] cmd = new String[3];
        cmd[0] = getJavaCommand();
        cmd[1] = "Cmd";
        cmd[2] = "foo bar\\baz\\";
        System.err.println("parent: " + cmd[2]);

        Process process = Runtime.getRuntime().exec(cmd);
        InputStream in = process.getErrorStream();
        byte[] buf = new byte[1024];
        int n;
        while ((n = in.read(buf)) >= 0)
            System.out.write(buf, 0, n);
 
    }

}

-- Expected output

parent: foo bar\bazchild: foo bar\baz
-- Actual output

parent: foo bar\bazchild: foo bar\baz"
