LSP server crashes repeatedly in VS Code Yangster extension - InaccessibleObjectException

When I open Visual Studio Code to the OpenConfig project, the LSP server crashes repeatedly.

Steps to reproduce

Install JDK 17
Install VS Code and install https://marketplace.visualstudio.com/items?itemName=typefox.yang-vscode
git clone http://github.com/openconfig/public/
code ./public/

My java version:

java -version
openjdk version "17" 2021-09-14 LTS
OpenJDK Runtime Environment Corretto-17.0.0.35.2 (build 17+35-LTS)
OpenJDK 64-Bit Server VM Corretto-17.0.0.35.2 (build 17+35-LTS, mixed mode, sharing)

Log output

The Output window for "Yang Language Protocol" show a stack trace of errors. The most recent one I see says

java.lang.reflect.InaccessibleObjectException: Unable to make protected final java.lang.Class

But there are others like

com.google.inject.internal.util.$ComputationException: com.google.inject.internal.util.$ComputationException: java.lang.ExceptionInInitializerError
