vscode-kotlin Language server does not find openjdk installation (sdkman)

Describe the bug When I want open up a kotlin file the language server fails to startup.

No Java runtime present, requesting install.
[Info  - 2:44:28 PM] Connection to server got closed. Server will restart

I also get the modal To use the "java" comand-line tool you need to install a JDK.

To Reproduce Steps to reproduce the behavior:

Open up a *.kt file

Expected behavior The language server succeeds in starting

Extension version 0.2.11

Additional context I am using sdkman and have openjdk 11 and kotlin 1.3.72 installed and set to default. java is accessible in the path and JAVA_HOME is set. OSX Catalina.

Facing same issue

May 19 '20 12:05 ghost

I am facing the same issue with the amzn release of java, installed with sdkman using: java 8.312.07.1-amzn (set by default for the project directory) java 11.0.13.8.1-amzn (attempted with this version as well, manually set via sdkman command)

! Error is Java Language Server requires a JDK 11+ to launch itself. The java.home variable defined in Visual Studio Code settings points to a missing or inaccessible folder (/Users/foobar/.sdkman/candidates/java/11.0.11.9.1-amzn)

I found that a deprecated setting in VSCode settings.json was overriding the preferred setting:

    "java.home": "/Users/foobar/.sdkman/candidates/java/11.0.11.9.1-amzn",
   ...
    "java.jdt.ls.java.home": "/Users/foobar/.sdkman/candidates/java/11.0.13.8.1-amzn"

java.home is deprecated, but for some reason is taking precedence over the newer setting.

I've JAVA_HOME set up:

$ echo $JAVA_HOME
/home/us-er/.asdf/installs/java/openjdk-17

$ java --version
openjdk 17 2021-09-14
OpenJDK Runtime Environment (build 17+35-2724)
OpenJDK 64-Bit Server VM (build 17+35-2724, mixed mode, sharing)

$ kotlin -version
Kotlin version 1.8.21-release-380 (JRE 17+35-2724)

But still I see this error:

Not sure if @fwcd's https://github.com/fwcd/vscode-kotlin/commit/591771f2137f45a13e24db52c0aca05a2d04c335 has to do something with it.

This seems like a VSCode issue rather than asdf/rtx. Ref: https://github.com/microsoft/vscode/issues/187955
