Hi, In my case I used PDFBox, just to extract the text from PDF document and then I created the Lucene document giving the extracted text. (I didn't use the PDFBox built in Lucene search engine). So I didn't get any incompatibility problems.
This blog post shows the way. http://kalanir.blogspot.com/2008/08/indexing-pdf-documents-with-lucene.html It worked perfect for me. Thanks.
