The minimum environment need to set is SystemRoot, using harmony6 and drlvm

[Charles Lee]

Hi guys,

I am running the selected[1] test cases against the harmony6 + drlvm. My
local properties is:

os: windows xp professional sp2
sdk: visual studio 2008
link: Microsoft (R) Incremental Linker Version 9.00.21022.08

Only one test case fail on my
site: org.apache.harmony.archive.tests.java.util.jar.JarExecTest

Running test case below[3], RI returns the version of its java but harmony
return nothing but the error code -1072365564 (0xC0150004). harmony can not
initialize the java command successfully. If I add the SystemRoot
environment (uncomment the code which is commented), harmony will pass test
case[3].

1. Will anybody test [3] using vs2003? will it pass building with vs2003?
2. Why we need SystemRoot on windows?
3. I can add the environment SystemRoot in the java code; or add the
SystemRoot in the Runtime_win.cpp in drlvm; any other good solution to this
problem?

[2] I am not running lang-management test cases, because it will hang on my
machine.
[3] public static void main(String[] args) throws Exception {
        Runtime rt = Runtime.getRuntime();
        String javaHome = System.getProperty("java.home");
        System.out.println(javaHome);
        String command = javaHome + "/bin/java -version";
//        String systemRoot = System.getenv("SystemRoot");
//        System.out.println(systemRoot);
//        String envSystemRoot = "SystemRoot="+systemRoot;
        String[] envp = new String[] {"A=B", /*envSystemRoot*/};
        Process p = rt.exec(command, envp);
        p.waitFor();
        System.out.println("Exit value: " + p.exitValue());
        InputStream in = p.getInputStream();
        int read = -1;
        while ((read = in.read()) != -1) {
            System.out.print((char)read);
        }
        System.out.println();
        in = p.getErrorStream();
        read = -1;
        while ((read = in.read()) != -1) {
            System.out.print((char)read);
        }
        System.out.println();
    }
