If I do that, the only objects I get are:

Paint.Picture
Packager Shell Object

The length of the byte[] getObjectData returns is 0.

If I iterate over the entires in the Packager Shell Object (which is the 
object containing the embedded exe), I get the following children (The 
last number is object size via DocumentEntry.getSize():
Packager Shell Object.CompObj 76
Packager Shell Object.Ole10Native 180012 <--- these are the bytes I 
want, the Ole10Native entry is not contained in the output from 
workbook.getAllEmbeddedObjects()
