Issue Type: Bug

I have been using a very small project for a few months now, and have had the best experience with the Java Language support. Intellisense was working great until the last 2 patches of Visual Studio Code, which apparently broke the extension. It throws an exception, and then all IntelliSense stops working, including the JS/TS extension. If I restart Visual Studio Code, it will start working again, until it hits the exception again. Here are the details:

    I stopped by to say that I'm having a similar issue. Intellisense will randomly stop after using VS Code for some time; it seems to break when loading certain method suggestions after typing a dot. After that, Intellisense stops completely.

    I get the following javascript errors in the console when this happens (not sure how to see the java exceptions @ccerghed reports however).

    I am running Windows 10 and VS Code 1.37.1 as well.

    As an update, I can consistently trigger the Javascript errors when typing "System."

    Is anyone looking at this? I may have to use a different tool as intellisense breaking frequently is disruptive

    @maxi-billion can you provide the message output after turning on verbose tracing?

    The javascript errors don't appear to be any different after enabling verbose tracing. The server log file also doesn't appear to report anything scary, but here it is anyways. This is in the timeframe of typing "System." to trigger the issue

    @maxi-billion Could you disable the Spring Tools and Visual Studio IntelliCode extension and try to reproduce the issue?

    @snjeza You nailed it! With Visual Studio IntelliCode disabled, the plugin does not fail anymore.

    From searching IntelliCode in the issues here, it would seem this is a known issue, so I apologize.

    Thank you, I disabled IntelliCode and it fixed the issue for me as well.
