Extension overwrites JAVA_HOME set by Nix with SDKMAN!

I use Nix to manage my JDKs. All Nix packages for the different JDK distributions also configure the JAVA_HOME environment variable. This configuration takes precedence over SDKMAN!. In fact, from a Terminal window, everything works correctly. However, when opening the project in Visual Studio Code, the "Language Support for Java(TM) by Red Hat" extension seems to overwrite the value set by Nix with the one from SDKMAN!, even if there's no .sdkmanrc file in that project and the whole session is within the Nix environment context.

I have created a repo with a minimal setup and detailed instructions to reproduce the error (issue number 2 in the README).

从 issue 中链接的最小复现仓库开始，按照其 README 中的 issue 2 操作。比较终端中的 JAVA_HOME 与在 Visual Studio Code 中打开项目时的值，同时包括 session 的 Nix 上下文以及不存在 .sdkmanrc 文件这一点。完成的标准是，在此设置下 extension 不再覆盖 Nix 的 JAVA_HOME。
