Re: [cross-project-issues-dev] Announcing JDK 9 support for Eclipse Neon

[Jayaprakash Arthanareeswaran <jarthana@xxxxxxxxxx>]

Thanks Stephan for pitching in.

As Stephan said, we currently have no support for modules in Eclipse. In fact, we are still discussing what a module needs to be in 'Eclipse'. Feel free to join the discussion in bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=479483.

Regards,
Jay

Jay may correct me, but I'd describe it as such:

JDK 9 no longer ships the runtime libraries as a set of jars (rt.jar ...),
but as jimage files, the technical format of which is not subject to standardization.
Instead, API is provided for reading the content of such image.
(Hence: "proprietary format").
The BETA feature provides support for working with these jimage files.

By contrast, true Java 9 support would include support for the new
*language features* around Java modules. With the existing BETA feature
it is _not_ possible to create / compile / assemble such modules.
Compiler work in this area is only (shyly) starting just now.

any clearer?
Stephan
