-----------------------------------
Summary: JBIG2Filter is creating an ImageInputStream (with temp
file) and not closing it
Key: PDFBOX-1888
URL: https://issues.apache.org/jira/browse/PDFBOX-1888
Project: PDFBox
Issue Type: Bug
Affects Versions: 1.8.4
Environment: Java 1.6.0.
levigo-jbig2-imageio-1.6.1.jar
Reporter: Tim Cameron
Our application is processing JBIG2 encoded PDFs and is not restarted on a
regular basis. When calling pdPage.convertToImage() a temporary file is created
and never closed. After some time, the limit (1024 in our case) for open file
handles is being hit and we cannot process any more documents. I debugged the
code and found the culprit to be pdfbox/filter/JBIG2Filter.java. It is calling
ImageIO.createImageInputStream() to create a new ImageInputStream for the
ImageReader, but this stream is never being closed. A temporary file is being
created (/tmp/imageio<randomNumber>.tmp) as part of this call and remains open
if the stream isn't closed.
