OutOfMemoryError with PDFTextStripper
-------------------------------------
Key: PDFBOX-899
URL: https://issues.apache.org/jira/browse/PDFBOX-899
Project: PDFBox
Issue Type: Bug
Components: Text extraction
Affects Versions: 1.3.1
Environment: java version "1.6.0_22"
Java(TM) SE Runtime Environment (build 1.6.0_22-b04)
Java HotSpot(TM) Client VM (build 17.1-b03, mixed mode)
Reporter: Alexander Veit
Priority: Critical
PDFBox 1.3.1 has high memory demands when stripping text from PDF files.
http://www.unicode.org/Public/5.1.0/charts/CodeCharts.pdf even crashes an
application server by requiring esimated aditional 300MB+ of heap memory. The
heap dump suggests that PDFStreamEngine#documentFontCache might be the root of
the leaking objects.
PDFBox 1.0.0 did not show this behaviour.
