Well, yes, you clearly do misunderstand me completely.

In your scenario you describe applications as being supplied with libraries. Presumably those libraries can be 
upgraded/patched without it being necessary to re-download the entire application and re-install it?

Also, if different applications share the requirement for the same library you only need to have 1 copy of that library, 
not a different copy for each application?

Maybe Windows is different, and application developers think differently, but on Linux if I install/develop an 
application which, for example, requires access openSSL libraries I wouldn't expect those libraries to be statically 
linked into the application requiring the application to be downloaded and re-installed every time there was a change to 
openSSL. I would expect to be able to upgrade the library via a different route, and the application will get the latest 
update automatically via dynamic linking. The same applies to the "big jar" application. If any of the jar's bundled 
into the "big jar" were updated the application wouldn't benefit from that change until the application developer 
supplied you with an updated application, and you'd have to re-install the entire application all over, rather than just 
the updated library jar.
