RejectRouterHandler.FAIL does not work as intended. #6498
Description
Aremeria has three types of RejectRouterHandler.
DISABLEDWARNFAIL
However, both WARN and FAIL ultimately only produce warning logs, and the server builds successfully.
Therefore, to preserve the intended behavior of FAIL, the server build should fail when FAIL is used.
Server.builder()
.virtualHost("foo.com")
.rejectedRouteHandler(RejectedRouteHandler.FAIL)
.service("/foo", (ctx, req) -> HttpResponse.of("ok"))
.service("/foo", (ctx, req) -> HttpResponse.of("duplicate"));
