spring-loaded: The type registry does not know about type id

I’m receiving the following exception when using hot-reload with the Lettuce Redis library:

Caused by: java.lang.IllegalStateException: The type registry TypeRegistry(id=1346265082,loader=java.net.URLClassLoader) does not know about type id 901

Here is the line in question:

protected void safeSet(CommandOutput<K, V, ?> output, ByteBuffer bytes, RedisCommand<K, V, ?> command) {
    safeSet(() -> output.set(bytes), command);
}
