潘冠敬 commented on PDFBOX-107:
----------------------------
hi,The reason of the viewer crashed is the JFrame.setVisible(true) not
blocked,so it will throw "IOException : handle is not useable",when you call
the
PDDocument.close() method. Because this is earlier called than
PDFPagePanel.paint() method.The follows can fix the problem:
1.Use the model JDIalog replace the JFrame
2.call the PDDocument.close() after PDFPagePanel.paint() every time.
