Eclipse basically started out as a port of the VisualAge for Smalltalk environment to Java.

And they still keep a very tiny bit of it on the "Java Browser" perspective, which is basically the standard way Smalltalk presents the code navigation.

That port was horrible. It was only when they dumped the smalltalk codebase and started again that it became useful.

Pretty much par for the course for those days. Converting Smalltalk apps to Java ones usually yielded horrble Java apps, because Java was very immature, to be frank. While it was still VisualAge for Java, it was considered one of the best Java IDEs of the time.
