Tilman Hausherr commented on PDFBOX-3887:
-----------------------------------------
The last commit makes PDFBox even more lenient, it accepts the total loss of an
object stream. I'm now able to extract some of the text. It fails after some
time. If the purpose of your application is to extract as much as possible e.g.
for indexing, then do the extraction page by page and don't stop on exceptions.
Apache Tika has such an option.
This commit may be reverted if we find regressions on pre-release mass tests
(which includes many corrupt files).
