             Summary: java.io.IOException: Object at offset does not end with 
'endobj'
                 Key: PDFBOX-1811
                 URL: https://issues.apache.org/jira/browse/PDFBOX-1811
             Project: PDFBox
          Issue Type: Bug
    Affects Versions: 2.0.0
         Environment: XP, W7
            Reporter: Tilman Hausherr


I get this exception with the file amyuni2_05d__pdf1_3_acro4x.pdf (it was once 
part of the project, now no more, but it can still be found on the web):
java.io.IOException: Object (48:0) at offset 161333 does not end with 'endobj'.

This is true, the "endobject" is indeed missing in that file. However the 
content of endObjectKey is 49 0 obj, i.e. the start of a new object.

So my suggestion is to change in NonSequentialPDFParser.java the segment at

{code}
if (!endObjectKey.startsWith("endobj"))
{
      throw new IOException("Object (" + readObjNr + ":" + readObjGen + ") at 
offset "
                    + offsetOrObjstmObNr + " does not end with 'endobj'.");
}
{code}

to
{code}
 if (!endObjectKey.startsWith("endobj"))
 {
     if (endObjectKey.endsWith(" obj"))
         LOG.warn("Object (" + readObjNr + ":" + readObjGen + ") at offset "
             + offsetOrObjstmObNr + " does not end with 'endobj' but with '" + 
endObjectKey + "'");
     else
         throw new IOException("Object (" + readObjNr + ":" + readObjGen + ") 
at offset "
             + offsetOrObjstmObNr + " does not end with 'endobj' but with '" + 
endObjectKey + "'"); }
{code}
