cassandra.bat throws java.io.IOException: rename failed of LocationInfo-e -1-Data.db in 0.7rc1

I've followed the Getting Started instructions for single node and it worked fine in cassandra-0.7beta2. But when trying to do the same for cassandra-0.7rc1 it spews out the开发者_运维知识库 following stack trace:

Someone posted this problem on cassandra's mailing list. It seems there's a problem, when trying to rename the tmp files (e.g. LocationInfo-tmp-e-1-Data.db). It happens in FBUtilities.java:

public static void renameWithConfirm(String tmpFilename, String filename) throws IOException
    {
        if (!new File(tmpFilename).renameTo(new File(filename)))
        {
            throw new IOException("rename failed of " + filename);
        }
    }

I should note that File.renameTo() is known to work funny on Windows.

Anyway... Help?
