Subject RE: ClassFileSet method of loading classes

So how exactly are dependencies found then?  Are dependencies only found
when you instantiate something with the keyword "new"?  My code is
filled with objects that are instantiated from factories or services.
If I simply return these objects from a service to my base code will my
base code not see this class as a dependency?  I use these objects all
throughout the base code, so I would imagine that they would be seen as
such.

When you examine at the bytecode of your (root-)class you will see that 
writing

   MyClass.class

is totally equivalent to

   Class.forName("package-of-myclass.MyClass");

In fact, in bytecode it is coded much more near to the latter form, such

that looking the bytecode can't result in finding any dependencies to 
MyClass.

Some time ago, when I started to use an obfuscator, I ran into this 
obstacle, too.
