There are no available Samebug tips for this exception. Do you have an idea how to solve this issue? A short tip would help users who saw this issue last week.

  • We have found that update the pdfbox library to the last stable version (1.2.1) solve all our current issues with pdf text extraction and improve performance. This could help people that want rely on the DSpace "out-of-box" pdf extractor without using XPDF. Below some samples of exception that go away updating the pdfbox version.
