Thanks. This works but I've left some comments on improving it.

Can you also add a change log entry under 5.3.0?

Maybe helper method? ENVP_WINDOWS and ENVP_UNIX constants.

private static String[] getDefaultEnv() {
    if (platform == PlatformEnum.WINDOWS) {
        return ENVP_WINDOWS;
    } else if (platform != PlatformEnum.UNKNOWN) {
        return ENVP_UNIX;
    } else {
        return null;
    }
}

Maybe helper method?

In the direction I was thinking but this will not change during operation, so we just need a one-time constant (So using this helper method but defining a constant as the result would work).

Pushed review fixes.
