Installing the VSCode extension pack for Java runs a headless version of Eclipse JDT under the hood, which isn’t quite what I think of as lightweight.
What's wrong with that? If they re-implement the whole thing it would amount to the same code size. It's the JDT language SERVER not some sort of "headless" software with UI needlessly bundled.
Java isn't quite what I think of as lightweight. I mean it probably can be, but most Java engineering I know of is all about adding more and more libraries, frameworks, checks, tests, etc.
