Page not found after deploying micronaut app to Java11

I have deployed micronaut-hello to Java11 runtime with no modifications other than (1) using my existing project, and (2) adding one line to app.yaml:

runtime: java11
instance_class: F1
service: hello

When I try to access this service in a browser, I get the following message, which seems like it’s coming from micronaut:

{“_links”:{“self”:{“href”:“/”,“templated”:false}},“message”:“Page Not Found”}

What may cause this?

The other services in this project work on Java8 as expected.

@averikitsch, are you the right person to take a look?

@kurtisvg it’s most likely more of a micronaut using maven problem. I’m not sure how to dig into it more, but I believe it’s a conflict with the annotationProcessorPaths used with micronaut and error prone. Removing error-prone from the parent solves the problem.
