JetBrains ships IntelliJ IDEA's Java and Kotlin intelligence as an LSP extension for VS Code and Cursor

Sources: announcement, discussion
Summary: JetBrains packaged IntelliJ IDEA's Java and Kotlin language intelligence as a language server and shipped it as an extension for VS Code and Cursor. JetBrains states the driver is agentic development rather than editor choice, and names terminal agents such as Claude Code and Codex as the next target.
Why it matters: Java and Kotlin refactoring accuracy stops being a reason to keep a second IDE open, and an agent that can query a language server resolves types by lookup instead of rediscovering them from source.
