Hi, I am using PDFBox to extract text. Here is the code:
PDFTextStripperByArea stripper = new PDFTextStripperByArea();
stripper.addRegion("cropbox", rec);
stripper.setSortByPosition(true);
Line "stripper.setSortByPosition(true)" causes the following error:
Exception in thread "main" java.lang.IllegalArgumentException:
Comparison method violates its general contract!

Is this a bug? Is there a fix I can use?
