Jukka Zitting commented on PDFBOX-778:
--------------------------------------

Which version of PDFBox are you using? With PDFBox 1.2.1 I'm able to extract the text of this document with only 16MB of heap.

    $ java -Xmx16m -jar pdfbox-app-1.2.1.jar ExtractText 92.pdf
    $ wc 92.txt
      513  4792 35080 92.txt
    $ java -version
    java version "1.6.0_20"
   Java(TM) SE Runtime Environment (build 1.6.0_20-b02)
    Java HotSpot(TM) Client VM (build 16.3-b01, mixed mode, sharing)
