VS Code Java Cannot Run from Read-Only Location

[tsmaeder]

When running VS Code Java, some files are created in server\config_win\org.eclipse.core.runtime (this is on Windows, but likely not Windows-specific).
The problem with this is that you cannot run VS Code Java from a location where you don't have write access. This prevents VS Code Java from running as a built-int extension in Theia, for example.
To me it seems that the files in question are created by the eclipse configuration management. IMO, those files should be created in the directory obtained from ExtensionContext#globalStoragePath. Eclipse has a startup parameter to set the osgi configuration area (see here and here)
