Unhandled exception in router
I dont know what this causes and I dont know how to get rid of it

Do you have a reproducer?

Nope, thats the problem.

Code:

Vertx vertx = Vertx.vertx();
if (vertx instanceof VertxInternal vertxInternal) {
	BlockedThreadChecker blockedThreadChecker = vertxInternal.blockedThreadChecker();
	
	blockedThreadChecker.setThreadBlockedHandler(event -> {
		final String message = "Thread Thread[" + event.thread().getName() + "," + event.thread().getPriority() + "," + event.thread().getThreadGroup().getName() + "] has been blocked for " + (event.duration() / 1_000_000) + " ms, time limit is " + (event.maxExecTime() / 1_000_000) + " ms";
		
		RuntimeException rte = new RuntimeException(message);
		rte.setStackTrace(event.thread().getStackTrace());
		rte.printStackTrace();
	});
}

Router router = Router.router(vertx);
router.route().handler(SessionHandler.create(LocalSessionStore.create(vertx))
	.setSessionCookieName("session")
	.setCookieSameSite(CookieSameSite.LAX)
	.setCookieSecureFlag(true)
);
router.routeWithRegex("/files/.*").handler(this::handleFileRequests);
router.route().handler(BodyHandler.create().setBodyLimit(-1)).handler(this::handleRequests);
router.route().failureHandler(routingContext -> {
	Throwable failure = routingContext.failure();
	if (failure != null) {
		Web.log("Folgender Fehler ist aufgetreten: " + failure.getMessage());
		failure.printStackTrace();
	} else {
		Web.log("Unbekannter Fehler aufgetreten.");
		Web.log("Anfrage URL: " + routingContext.request().absoluteURI());
		Web.log("Requested URL: " + routingContext.request().path());
		Web.log("HTTP-Methode: " + routingContext.request().method());
		Web.log("Header: " + routingContext.request().headers());
		Web.log("Body: " + routingContext.body().asString());
		Web.log("Port: " + port);
			String forwards = routingContext.request().headers().get("X-Forwarded-For");
		String ip;
		if (StringUtils.isNotBlank(forwards)) {
			ip = StringUtils.substringBefore(forwards, ",");
		} else {
			ip = routingContext.request().remoteAddress().host();
		}
		Web.log("IP: " + ip);
			if (routingContext.request().authority() != null) {
			boolean isHttps;
			if (routingContext.request().headers().contains("X-Forwarded-Proto")) {
				isHttps = routingContext.request().headers().get("X-Forwarded-Proto").equalsIgnoreCase("https");
			} else {
				isHttps = routingContext.request().isSSL();
			}
			Web.log("Host: " + ((isHttps ? "https://" : "http://")) + routingContext.request().authority().host());
		}
	}
	routingContext.response().setStatusCode(404).end();
});
