Parsing issues & duplicate objects

[Ad...@swmc.com]

I'm trying to find some solution to the problem of documents which have 
multiple objects with the same object ID and revision number.  I have some 
documents which cause NPE and hence the documents can not be merged.  I 
realize these are out of spec, but when the files are opened with Adobe 
Reader, they are rendered just fine.  So (non-technical) people figure if 
Adobe Reader can read it, why can't our software deal with it?

I found some code in COSObject::setObject() which seems to take a crack at 
solving this, but it's all commented out.  I uncommented it hoping it 
would magically solve my problems, but there was no such luck.  Does 
anyone know who wrote that code so I can collaborate with them (SVN 
history didn't have anything)?

According to Neil[1], the best thing to do would be to rewrite the parser. 
 I'm not beyond rewriting the parser if that will solve my issue.  But I 
need to understand how it currently works and how it should work before I 
can take on something like that.  I noticed that section 7.5.5 (File 
Trailer) of the PDF spec says "Conforming readers should read a PDF file 
from its end." and I'm pretty sure PDFParser::parse() doesn't do that.

Anyone think looking at the COSObject will be any faster than rewriting 
the parser?

The documents I have are all confidential, so unfortunately I can't share 
them, but there are some other[1] issues[2] which seem to be somewhat 
related.  I'm going to keep looking for a file I can get approved for 
release so I can upload it to JIRA with an exact stacktrace and 
everything.
