This happens every time working on any java project in vscode with the extension applied, with quick suggestions enabled, even if when i stop writing and waiting for the suggestions to appear it take long time to appear.
When i stop typing and pressing cmd+space instead it shows loading for a while until it shows the suggestions in the Intellisense.

Environment

• Operating System: Mac os
• JDK version: 1.8.0_45
• Visual Studio Code version: 1.8.0
• Java extension version: 0.0.7
