• code-server version: 1.604-vsc1.32.0
• OS Version: Ubuntu 18.04, running in systemd-nspawn container.
• Extension: https://marketplace.visualstudio.com/items?itemName=vscjava.vscode-java-pack

Description

When opening a Java file after installing the Java Extension Pack, the syntax highlighting works, but nothing else does - I don't get the rocket as described on https://code.visualstudio.com/docs/java/java-tutorial.

I have verified that the same setup works on desktop (Linux) VS Code.

I have installed OpenJDK 11 inside the coder container.

Steps to Reproduce

1. Install the Java Extension Pack from the marketplace
2. Try opening any Java file. See that no syntax errors or info is shown.
