Expected default value to be empty string but found null

[ambianBeing314]

I have a test endpoint:

@Get(value = "/test-default")
    HttpResponse<String> testDefault(@QueryValue(value = "test") @Nullable String test);

Its Implementation:

  @Override
  @ExecuteOn(TaskExecutors.IO)
  public HttpResponse<String> testDefault(String test) {
    System.out.println("Test::"+ test);
    return HttpResponse.status(HttpStatus.OK).body("All good!!");
  }

Calls:
http://localhost:8080/orders/test-default?test=sometext
Expected: test == sometext ✅

http://localhost:8080/orders/test-default
Expected or Assumed: test == "" ❌

According to @QueryValue the defaultValue defaults to "" empty string. So when printing the value of test the expectation was empty string but was instead null. I could be missing something very obvious though.
