COSVisitorException: The handle is invalid
------------------------------------------
Key: PDFBOX-497
URL: https://issues.apache.org/jira/browse/PDFBOX-497
Project: PDFBox
Issue Type: Bug
Components: PDModel
Environment: Windows Vista
Reporter: James A. Thomas
Fix For: 0.8.0-incubator
If I save a PDF document in a method of an application class, I get a
COSVisitorException: The handle is invalid.
--------------------------------------------------------------------------------------------------
I found that I no longer get this exception if I do not close the
PDDocument "DrawingDoc" in the method "addDrawing".
However, I do get a warning:
java.lang.Throwable: Warning: You did not close the PDF Document
at org.apache.pdfbox.cos.COSDocument.finalize(COSDocument.java:391)
