John Hewson commented on PDFBOX-2596: ------------------------------------- That sounds a lot like a multithreading issue... > NullPointerException in RandomAccessFileInputStream > --------------------------------------------------- > > Key: PDFBOX-2596 > URL: https://issues.apache.org/jira/browse/PDFBOX-2596 > Project: PDFBox > Issue Type: Bug > Affects Versions: 1.8.8 > Reporter: John Roche > > Line 94 contains a synchronized(file) that throws a NullPointerException > under some strange circumstances that I haven't been able to fully identify > yet. I have downloaded the 1.8.8 source and the fix I used is simply to add > "&& file != null" to the previous if statement. > I can reproduce this bug with live user data, but I haven't been able to with > test data yet. It happens when I try to create a pdf with 36 pages that have > an image, some drawn coloured boxes and some text, on each page. If I remove > some of the pages before I call save(File) it doesn't happen - depending on > which pages I remove it can be ok with up to 26 pages, or break with fewer. > Quite strange. I suspect it's to do with the size of the data as opposed to > the number of pages. > I will continue to investigate, since there seems to be some underlying > issue, but for now I guess the null protection should be ok to add? > Thanks, > John -- This message was sent by Atlassian JIRA (v6.3.4#6332)
