47-67: Consider removing unused Spring Boot dependencies.The PR transitions from Spring Boot to a Smithy-based HTTP server, yet the Spring Boot plugins (lines 4-6) and all Spring Boot starter dependencies remain. If these are no longer used, they add unnecessary bloat and potential classpath conflicts.
If this is an incremental migration, consider documenting a TODO to remove these dependencies once the transition is complete. Otherwise, remove them now.

createRoute currently reports success without creating a route.
Line 13 ignores input and returns a blank CreateRouteOutput, so callers can get a successful create response even though nothing was persisted or delegated downstream. Please wire this handler to the real create path, or fail explicitly until that implementation exists.

deleteRoute acknowledges deletes without deleting anything.
Line 11 ignores the request and returns success unconditionally, so clients can believe a route was removed while the backing state remains untouched. This needs to call the real delete path, or fail explicitly until it exists.

getRoute always returns an empty payload.
Line 11 never uses input to look anything up, so every request will succeed with the same blank response regardless of the requested route. Please delegate to the actual lookup path, or return a modeled not-found/not-implemented error instead of a successful empty body.

🧩 Analysis chain
🌐 Web query:
In Java, what happens when Thread.currentThread().join()is called from the current thread, and are JVM SIGINT/SIGTERM shutdowns delivered asInterruptedException on the main thread or through shutdown hooks?
💡 Result:
When Thread.currentThread.join is called from the current thread, the thread blocks indefinitely. The join method waits for the target thread to terminate by repeatedly checking isAlive and calling wait(0) on the thread's monitor while alive. Since the thread is waiting on its own monitor and cannot notify itself (as it's blocked), it deadlocks and never proceeds. This is a common idiom to prevent the main thread from exiting in server applications, allowing daemon threads to continue running until an external shutdown signal is received. JVM SIGINT (Ctrl+C) and SIGTERM shutdowns do not deliver InterruptedException to the main thread (or any application threads). These signals trigger the JVM's shutdown sequence: shutdown hooks are executed (if registered via Runtime.addShutdownHook), then the JVM halts. InterruptedException is only thrown due to explicit Thread.interrupt calls, not OS signals. The JVM handles SIGINT/SIGTERM internally without interrupting application threads; instead, it runs shutdown hooks for cleanup. Daemon threads continue during shutdown but are terminated when the JVM halts.

Thread.currentThread().join() will not trigger graceful shutdown on JVM termination.
Calling Thread.currentThread().join() blocks indefinitely and relies on InterruptedException to unblock. However, normal JVM shutdown signals (Ctrl+C, SIGTERM) do not interrupt application threads—they trigger shutdown hooks instead. This means server.shutdown().get() in the catch block will never execute during graceful shutdown, leaving server resources uncleaned.
Register a shutdown hook with Runtime.addShutdownHook() for graceful shutdown logic, and use a CountDownLatch or CompletableFuture to keep the main thread alive until shutdown is triggered. If catching InterruptedException, restore the interrupt flag before returning.
