Re: RFR: 8295884: Implement IDE support for Eclipse [v34]

[Julian Waters]

> Eclipse is a popular and very well-known IDE in the world of Java 
> development, utilized widely in many contexts, by beginners and experienced 
> teams alike. Although a relatively lightweight IDE, it features surprisingly 
> powerful indexing and code analysis capabilities, as well as useful tools, 
> among which are make integration. While the tools it provides are not always 
> as sophisticated as other IDEs (IntelliJ IDEA will likely come to mind as one 
> such competitor), the simplicity of using it, as well as the reliability of 
> this rugged IDE makes up greatly for the slightly less advanced tooling. 
> Eclipse requires very little starting infrastructure in the workspace for all 
> these features and indexing support as well, which makes it a good candidate 
> for developing on the JDK.

> including the Java Virtual Machine's source code, to generating a workspace
