Compilation errors not working with JDK 9/10/11

[oscarnylander]

Environment

• Operating System: macOS High Sierra Version 10.13.6 (17G65)
• JDK version: 9/10/11
• Visual Studio Code version: 1.27.2 x64
• Java extension version: 0.31.0

Steps To Reproduce

1. Set JDK version to 9/10/11 via the java.home setting
2. Restart editor
3. Wait for java language support to boot entirely
4. Observe lack of compilation (red underlining etc)

No compilation errors

Expected Result

Compilation errors

Additional Informations

We make heavy use of Lombok, could this be related?

I can confirm this issue.

• Operating system: Windows 10 1809
• JDK version: openjdk version "11.0.1" 2018-10-16
• Visual Studio Code version: 1.30.1
• Java extension version: 0.36.0

I have enabled Lombok support as documented here. lombok.jar is at the latest version (1.18.4) which should have sufficient JDK 11 support. Here is a basic Spring Boot Maven project that does compile and which reproduces the issue: https://github.com/johnno-vdv/vscode-java-openjdk11-lombok-issue
When JDK 11 is used all syntax checking will be disabled (the entire extension basically stops working). This exception is printed in the output window:

This is happening on my box too. I am on ubuntu, running openJDK 11, and NOT using lombok. Here is the error:

@JustAnotherSoftwareDeveloper did you override the jdt.ls.vmargs value in your vscode settings (or installed the vscode lombok extension)?

[JustAnotherSoftwareDeveloper]

No. I had vscode lombok installed at a previous time, but it has been uninstalled for a while. I have restarted everything since then.

[yaohaizh]

@JustAnotherSoftwareDeveloper The vscode-lombok will make change to the settings, not sure if you have revert the changes? You can find a related issue here: #743 to see whether it helps.

[JustAnotherSoftwareDeveloper]

This fixed it. I apologize for not checking vmargs immediately. I assumed because I hadn't touched it that nobody touched it.
