helloworld-new-plugins java-docs-samples seem to have issues when running locally.

When I run this sample from https://github.com/GoogleCloudPlatform/java-docs-samples/tree/master/appengine locally with command gradle appengineRun, than visit http://localhost:8080/_ah/api I get this exception:

Is it a bug or not? http://localhost:8080 opens normally

I think @chanseokoh might have some context on this.

[chanseokoh]

Very similar to GoogleCloudPlatform/app-maven-plugin#201, using the same sample app. However, the class that cannot be found is slightly different. It seems like GoogleCloudPlatform/app-maven-plugin#201 should have been fixed in the latest Cloud SDK. The internal bug says /_ah/api is no longer valid and should return 404. @diman4ik can you check your gcloud version with gcloud version? Never mind. I can reproduce this with the latest gcloud.

That sample doesn't have endpoints in it does it?

@diman4ik are you trying to run an endpoints application?

[chanseokoh]

Actually, I can just reproduce with the latest Cloud SDK by doing this.

$ git clone https://github.com/GoogleCloudPlatform/java-docs-samples.git
$ cd java-docs-samples/appengine/helloworld-new-plugins/
$ mvn appengine:run

So, I guess the internal bug 63715943 isn't fixed?

@diman4ik FYI, the local server is running OK. It's just that /_ah/api is for an Endpoints app, which does not apply to this sample. Seems like we have a minor bug that it is not returning 404 in this case.
