What is wrong with this picture ?

Can you point out the mistake in the following picture of this otherwise fully functional EOModeler application ?
Click on the image to see it in full resolution.

The obvious mistake is the version number of the EOModeler and the displayed list of available adaptors. Version 5.3 is used for Java WebObjects exclusively and the list contains a number of version 4.5 adaptors like MulleSybase and Oracle. The model loaded in the background is an Objective-C EOModel using the MulleSybaseEOAdaptor.

Now how could this happen ?

With the install_name_tool all EOF frameworks from /System/Library/Frameworks/ have been replaced with MulleEOF frameworks. The frameworks are binary compatible and functionally equivalent allowing EOModeler to run without recompile. EOModeler does not just use the model classes from EOAccess but also uses EOEditingContext for the manipulation of the models and EOInterface for it's display.
