The Language Server Protocol currently defined by the VSCode team at [1] is an effort to unify communication between editors (tools) and advanced language tooling.
[1] - https://github.com/Microsoft/language-server-protocol
This project aims at providing a reusable Java implementation of VSCode's language server protocol. It implements the types as well as the communication, including serialization to and deserialization from JSON.
LSP4J is a Java implementation of VSCode's language server protocol intended to be consumed by tools and language servers implemented in Java.
The Eclipse Foundation is a trusted open source foundation and hosts a number of potential clients of this project, such as (Eclipse Platform, JDT, Xtext, JSDT, etc.)
No legal issues.
We intend to provide a first incubation release shortly after project creation.
It is planned to keep up with the evolution of the language server protocol.

xtend or java ?
Submitted by Max Rydahl Andersen on Thu, 2016-07-28 09:52
The proposal says "LSP4J is a Java implementation of VSCode's language server protocol i" but https://github.com/TypeFox/ls-api is using XTend.
Is the plan to make this pure java ?
And we've taken a quite simpler approach afaics with the java languager server that uses json schemas which we hope to be adopted by the spec eventually.
Would this project be interesting adopting that approach ?

Hi Max,
yes to both.
See https://github.com/TypeFox/ls-api/issues/28 (although xtend generates java, so ls-api already is java)
Regarding the json. We are waiting fro MS to accept the according PR. But then we plan to generate the type defs from that.
Pleease add Red Hat to interested parties

Red Hat is definitely interested in this project and would like to be listed as interested parties.
Thank you Mickael! I added

Looking forward to seeing

Looking forward to seeing LSP4J as an Eclipse project. We are planning to adopt it in Cloudfier, and we hope Orion too will provide support for the Language Server Protocol as well.
Good to know! I've heard

Good to know! I've heard rumors of Orion going to support it, too.
It's much more than rumors:

It's much more than rumors: here is some experimental and encouraging progress: https://www.youtube.com/watch?v=A-jnqySRA50 . However, as it's not Java, I don't think Orion is directly interested in the LSP4J project. That said, I guess they'd be glad to share ideas/plans/work if you ask on their mailing-list.
Please add itemis to intersted parties
