> Key: PDFBOX-1305
> URL: https://issues.apache.org/jira/browse/PDFBOX-1305
> Project: PDFBox
> Issue Type: Bug
> Components: Text extraction
> Affects Versions: 1.6.0
> Environment: Same phenomena on Windows 7, Solaris 10 and CentOS 5.7.
> Same result with JDK 7u4 and JDK 6u32
> Reporter: Roger Håkansson
> Attachments: 20020101ab3x012a.pdf

>
> I've got 1.2M single-page PDF files which I'm indexing using Solr (which is
> using Tika, which is using PDFBox) and some of them takes between 20min up to
> an hour to index.
> This is a huge problem for me, in 48hours I've indexed about 45k files and 19
> hours of that time was spent on just 279 files.
> I've traced it to PDFBox taking a lot of time extracting the text from the
> documents.
> I've tested extracting the text using pdfbox-app's ExtractText with the same
> result, the text is extracted but it takes forever...
> The attached file took about 23min (using ExtractText) and from the result I
> can see a lot of "rubbish text" which I don't see in the text extracted from
> files that takes a normal amount of time (up to a few seconds per file) to
> parse.
> When running truss (on Solaris, strace on Linux) on the java-process, I can
> see a lot of SEGV due to FLTBOUNDS, which I don't know if its related to this
> problem but I just want to mention it.
