Ongoing Java language support
- Java language support is under-resourced
- short-term the effects may not be visible, but lack of support for the twice-yearly releases will make it harder long term as consumers start to transition to newer versions
- this issue is distinct from supporting running Eclipse itself on newer versions of Java
- language support umbrella bug is https://github.com/eclipse-jdt/eclipse.jdt/issues/40 for Java 20
