"Attempted to endRule: null, does not match most recent begin: R/" during "Classpath Update Job"

[savenkodenys-dev]

I have a project with the following structure:

portal-back/
├── portal
├── portal-commons
├── portal-gateway
├── portal-integration
├── portal-liquibase
├── portal-sync

All projects (portal, portal-commons, portal-gateway, etc) are java-applications which uses Gradle (with wrapper) as a build tool. All projects have written and compiled in Java 11, uses Gradle 6.1, except portal-commons which uses Gradle 5.2.1. All projects except portal-commons and portal-liquibase are Spring Boot applications.

I have been working on this project quite a while in VSCode, everything worked, but couple days ago this stopped working. The problem is that VSCode recognized only portal and portal-commons projects. I have done "Clean Workspace" and "Clean Java Language Server Workspace", moreover I have re-cloned the project in another directory and opened it again. Nothing helps. I think this happed due to extension update or something else but couldn't figure it out.

Environment

• Operating System: MacOS Big Sur 11.7.10
• JDK version: 11
• Visual Studio Code version: 1.88.1
• Java extension version: 1.30.0

java.jdt.ls.java.home is set to Java 17, java.import.gradle.java.home is set to Java 11.

Error message from Java Language Server Logs:

Current Result

VSCode doesn't load all nested Java-projects. If I open projects separately, for example, portal I got java.lang.ClassNotFoundException: portal.commons.support.LangKeyHandlerMethodArgumentResolver at runtime (class from portal-commons).

Expected Result

VSCode loads all nested Java-projects

[paulmedynski-microsoft]

I'm seeing the same error in the logs, and sometimes VSCode never completes the "Configuring charset for project ..." step.

I also notice that some Java syntax highlighting is broken. Imports are all white (no colour), variables are white when used without member/field access, among other things.
