Found possible Typo/Bug

[dsrmatze]

In RootTools.java:
retry should be passed through to the startShell and startRootShell function call.

public static Shell getShell(boolean root, int timeout, int retry) throws IOException, TimeoutException, RootDeniedException {
        if (root)
            return Shell.startRootShell(timeout);
        else
            return Shell.startShell(timeout);
    }

Suggested solution:

public static Shell getShell(boolean root, int timeout, int retry) throws IOException, TimeoutException, RootDeniedException {
        if (root)
            return Shell.startRootShell(timeout, retry);
        else
            return Shell.startShell(timeout, retry);
    }

Or explain why you dont pass it through in comments

Done, this is being passed through now.
