Not sure if any of those "Java Support" teams are really working on Apache Groovy support for VSCode -- they would be working on supporting growing JVM ecosystems (e.g. Java 11, Scala, Kotlin), not declining ones. Virtually every Grails stack out there is still using version 2, even though version 3 was released well over 3 years ago -- a sure sign of a declining ecosystem. Is the Grails stack you're working on any different?
