Description
So I'm trying to migrate from eclipse to vs code, all my projects are usually created using windows1252 for java files and utf8 for build/html/xhtml files, but when I try to run some projects that have special characters on enum names the compiler reports Syntax error for every single one of them, but when I open the files all the error messages disappear, if I close the file they return.

Environment
- Operating System: Windows 11 22H2
- JDK version: 17.0.6 and 11.0.10
- Visual Studio Code version: 1.77.2
- Java extension version: Project Manager for Java v0.21.2 Debugger for Java v0.49.1 | Language Support for Java(TM) by Red Hat v1.16.0
Project Settings
- Gradle 6.3
- Java 11
- Spring Boot 2.3.8.RELEASE
Steps To Reproduce
- Create a enum using windows1252 encoding and characters like ç ã é ú...
- Close the file and reload the project
Sample project for testing:
https://github.com/bernardomoraisbh/api-test
VS Code redhat.java/jdt_ws/.metadata/.log file:
https://pastebin.pl/view/e222cc93
Current Result
Compiler not working properly and error when running my spring projects over the Spring Dashboard Extension.
Expected Result
No compile errors and projects inside my workspace should be compiled with windows1252 encoding.
Additional Informations
I tried using the "spring-boot.ls.java.vmargs" settings for passing the encoding arg for the Spring Boot Dashboard extension, but I don't think it's working properly, since when I try to run the application over the dashboard I got only this args " & 'C:\R2DA\java\jdk-11.0.10\bin\java.exe' '@C:\Users\berna\AppData\Local\Temp\cp_2u4mmuey7f1wwsl3uwa1ds5ug.argfile' 'api.sistema.registro.ApiSistemaRegistroApplication'" and as soon as the application fails to start the file cp_2u4mmuey7f1wwsl3uwa1ds5ug.argfile is erased from the file system.
Contributor guide

- Fork the repository and make your change on a branch.
- Open a pull request that references the issue number.
Research direction
Start with the linked api-test sample project and reproduce the issue using the listed Windows, JDK, Gradle, and VS Code settings. Read the redhat.java/jdt_ws/.metadata/.log output and compare the project encoding with the Spring Dashboard launch argfile. Done means the sample project compiles and starts with windows1252-encoded Java enums after the files are closed.
