True, however since already the Visual Cafe, JBuilder and Visual Age days, Java IDEs have tried to provide a Smalltalk like experience, given where the community was coming from, so the concept of a virtual image mapped into the file system has always been present.

As such, code browsers always made this quite easy.

The fact that Eclipse provides a Smalltalk like code browser isn't an accident, rather its Visual Age roots.

It is only a problem when one makes the point to navigate through the source, outside Java tooling.
