java.configuration.runtimes option configuration error will not prompt an error

[Faputa]

I configured java.home as the installation directory of jdk11, and I deliberately set a non-existent path for JavaSE-1.8 in the java.configuration.runtimes option. Then when vscode opens Java8's project, the Java plug-in does not prompt for configuration errors, but used the jdk11 configured by java.home to compile and debug my project! This is a hidden trouble, If users misconfigure the path in the java.configuration.runtimes option, they will be more confused when the error occurs, just like I did before: vscode-java-debug/issues/873

Environment

• Operating System: Windows 10
• JDK version: openjdk version "1.8.0_265"
• Visual Studio Code version: 1.49.0
• Java extension version: 0.66.0

Current Result

Expected Result

When the path configuration of the java.configuration.runtimes option is incorrect, an error is displayed

Thanks for reporting, it's dup with #1481.

I believe @testforstephen is already working on this issue.
