Failed to decode downloaded font in Angular 5

EDIT: I can say with relative clarity, that it is an issue with my Spring application. Uploading it in my test-firebase, such a warning isn't being triggered.

Dear fellow coders...

Trust me when I say, I really tried going through the numerous other explanations posted in other people's questions. It's just an awfully curious case.

I wanted to try out to deploy my Angular 5 application in a Spring backend. It's really a barebone setup that looks like this...

 @SpringBootApplication public class AngularApplication extends SpringBootServletInitializer { @Configuration @EnableConfigurationProperties({ ResourceProperties.class }) public class WebMvcConfig implements WebMvcConfigurer { @Autowired private ResourceProperties resourceProperties = new ResourceProperties(); @Override public void addResourceHandlers(ResourceHandlerRegistry registry) { long cachePeriod = resourceProperties.getCache().getPeriod().getSeconds(); final String[] staticLocations = resourceProperties.getStaticLocations(); final String[] indexLocations = new String[staticLocations.length]; registry.addResourceHandler( "/**/*.css", "/**/*.js") .addResourceLocations(staticLocations) .setCacheControl(CacheControl.maxAge(cachePeriod, TimeUnit.SECONDS)); registry.addResourceHandler( "/**/*.html", "/**/*.json", "/**/*.bmp", "/**/*.jpeg", "/**/*.jpg", "/**/*.png", "/**/*.ttf", "/**/*.svg", "/**/*.eot", "/**/*.woff", "/**/*.woff2" ) .addResourceLocations(staticLocations) .setCacheControl(CacheControl.maxAge(60, TimeUnit.SECONDS)); registry.addResourceHandler("/**").addResourceLocations(indexLocations).resourceChain(true) .addResolver(new PathResourceResolver() { @Override protected Resource getResource(String resourcePath, Resource location) { return location.exists() && location.isReadable() ? location : null; } }); } } public static void main(String[] args) { SpringApplication.run(AngularApplication.class, args); } protected SpringApplicationBuilder configure(SpringApplicationBuilder application) { return application.sources(BizviewAngularApplication.class); } } 

I do a productive build of my application, put it in the static folder of my Spring application and run it. Looks and feels great, all in all. No errors, I can see my pages just fine with literally every browser. Edge, Opera, Firefox, but ONLY in the Chrome browser, I have one warning popping up which multiplies when the window is redrawn...

Failed to decode downloaded font and OTS parsing error: invalid version tag. I deleted font-awesome and re-installed 4.7, but this didn't help. The weird part is, the font-awesome icons are all perfectly fine. I can see them and none are missing from the project. I mean, it's my first application that I roll out, so I might be missing something, but it appears like an oddly specific issue
