Exception in thread "main" java.io.IOException: block[ 10 ] already removed - does your POIFS have circular or duplicate block references?

I think this line gives error
HWPFDocument doc = new HWPFDocument(in);
That is a problem in POI's hwpf support. You might try their most recent code.
Alternatively, I have had good results with OpenOffice v3.x (the Novell version) and http://code.google.com/p/jodconverter/
I am likely to remove the hwpf code from docx4j.
There is also http://b2xtranslator.sourceforge.net/ but its not Java.
