Description
URL of the problematic pdf file is http://www.redalyc.org/pdf/540/54017220.pdf
My program tries to extract the fulltext of the given pdf file in the following manner:
String fileName = "/home/sascha/testfile.pdf" // 1 PDDocument pdDoc = PDDocument.load(fileName, true); // 2 PDFTextStripper text = new PDFTextStripper(); // 3 String fullText = text.getText(pdDoc); // 4
The call in line 4 causes the thread to block indefinitely (runs now for more than two days without making any progress). The file is stored in a local file system (no network interaction occurs).
jstack indicates that the thread is not deadlocked:

Any idea or advice on how to fix that problem? Is it possible to set up a timeout for the extraction operation?
