Description

The themes from the META-INF/keycloak-themes.json file are parsed during the runtime. It'd be good to move it left to the build time. There's also some additional parsing of .properties.

 protected void loadThemes(ClassLoader classLoader, InputStream themesInputStream) {
        try {
            loadThemes(classLoader, JsonSerialization.readValue(themesInputStream, ThemesRepresentation.class));
        } catch (Exception e) {
            throw new RuntimeException("Failed to load themes", e);
        }
    }

Class ClasspathThemeProviderFactory.

Mitigation

Parse themes during build time and produce it to runtime (if possible)
