Tim Allison commented on TIKA-1228:
-----------------------------------
Y. That's the point of open source. :) Enjoy!
Now that I'm looking at this issue again, I dragged out some of my pre-Tika
code for pdf attachments using a different pdf library. It looks like the pdf
files I was coding against could have the file name in a parent node and the
actual bytes in a child or more distant descendant node.
Will see if I can dig up the triggering files and see if Tika needs any more
mods on PDF attachment extraction.

private MyPDFAttachment lookForByteStream(COSDictionary dict, MyPDFAttachment
attach, int recursiveDepth){
COSName fCOSName = COSName.create("F");
COSName efCOSName = COSName.create("EF");
COSObject fObj = dict.get(fCOSName);
COSObject efObj = dict.get(efCOSName);
if (null != fObj){
if (fObj.getClass() == COSString.class){
attach.setName(fObj.stringValue());
} else if (fObj.getClass() == COSStream.class){
attach.setBytes(((COSStream)fObj).getDecodedBytes());
return attach;
}
}
if (null != efObj && efObj.getClass() == COSDictionary.class){
int tmpI = recursiveDepth;
tmpI++;
return lookForByteStream((COSDictionary)efObj, attach, tmpI);
}
return null;
}
