> The problem occurs with moveToPrevious() case and incase of tags we copy the previous
pointer's tag info to the current because already decoded the tags.
> Will check once again before I post other details.  I have a test case to reproduce the
problem. Found this while working with MultibyteBuffers and verified if this is present in
trunk - it is in all branches where we have tags compression (I suppose) will verify
