Josiane Gamgo commented on PDFBOX-534:
--------------------------------------
I have the same kind of errors as in the description. Those errors doesn't
affect the indexing of Pdf files. But it would be nice to remove them.
I'm using Pdfbox to extract text from Pdf for indexing with Lucene.
This is what comes out :

> I'm getting an unexpected behavior parsing a pdf file.

> ExtractText.main(args);
> I used the PDFBox 0.8.0-incubator version. Builded on 20/9/2009.
