IntelliSense FAILS In Java, Macos

🐛 Bug Report

IntelliSense WORKS when I write code in other files.
However, IntelliSense FAILS when writing code using this extension.
In MACOS, JAVA.

I don't know whether it was on purpose, but It is very unfriendly to Newcomers. Because they don't familiar with the methods. So I switched to IDEA plugin version.
