Hi, Ravi,
I used your NullDirectory.java, and found it works fine for smaller indexes, but when it comes to larger indexes(I am not quite sure, just observation), it always throws this exception at here:
private void refill() throws IOException {
long start = bufferStart + bufferPosition;
long end = start + BUFFER_SIZE;
if (end > length) // don't read past EOF
end = length;
bufferLength = (int)(end - start);
if (bufferLength == 0)
throw new IOException("read past EOF");
....The print out and stack trace are:

Is there any way to detect the index's integrity?
Sometimes I came upon exceptions like these. If it happens, my only way is to delete the corrupted index.
* Exception in thread "main" java.io.IOException : read past EOF
* java.lang.ArrayIndexOutOfBoundsException

I did too, which is why I wrote NullDirectory. You can find the sources and a description in bugzilla.

Look at the tests for examples of use. I would value your feedback.
