That's a bold move! A LSP server for the price of an Ultimate license… I hope people will see the value 😓 I'll try it and hopefully it will nicely improve the @claudecode.bsky.social code generation, refactoring, and context awareness 💪

Oracle just published the “OpenJDK Interim Policy on Generative AI” 👀 openjdk.org/legal/ai This could have real impact on how we contribute to OpenJDK going forward. What do you think about it? Good direction or too restrictive?
openjdk.org
OpenJDK Interim Policy on Generative AI
The field of generative AI is evolving quickly. It brings compelling opportunities to improve developer productivity, but it also brings risks: to reviewer burden, to safety and security, and to intellectual property.
