Fall back to java.jdt.ls.java.home if embedded JRE fails

When deploying VSCode to an AP Computer Science lab where the students don't have admin privileges, attempts to enable the latest Extension Pack for Java (which includes the “Language Support for Java(TM) by Red Hat” extension) fail reporting “Couldn’t start client Language Support for Java” whenever they open a Java project.

Environment

• Operating System: Windows 10
• JDK version: Various (tried latest Microsoft OpenJDK 11 & 17 as well as those from Adoptium's Teemurin)
• Visual Studio Code version: 1.64.0
• Java extension version: v 1.1.0 through v1.3.0

Steps To Reproduce

1. Install latest VSCode and JDK (with JAVA_HOME set correctly)
2. Create a new Java class

Current Result

Reports “Couldn’t start client Language Support for Java” when trying to run or debug the Java code.

Expected Result

Should work like it does for users with admin privileges (or how it did for v1.0.0).

Additional Information

Works fine for users with admin privileges or if we roll the students back to v1.0.0 of this extension. Typing java -version in terminal returns correct OpenJDK version.

まず、Java プロジェクトを使って Windows 10 で失敗を再現し、埋め込み JRE のパスと java.jdt.ls.java.home 設定を比較します。管理者権限のないユーザー、および JAVA_HOME が設定されている場合の動作を確認します。Language Support for Java クライアントが起動し、管理者アクセスを必要とせずに Java コードを実行またはデバッグできれば完了です。
