/cc @ebullient, @jmartisk @brunobat

Also cc @mkouba in case this is an Arc issue

Removed area/smallrye, the reproducer is using Micrometer

I think this use case can't work, RemoteApiSingleton is not a CDI bean at all in your application, therefore the metric interceptors don't apply. It's just a POJO returned from a producer, and you build it by calling its constructor directly. Annotated metrics only work on CDI beans.

[mkouba]

@jmartisk is right. In CDI, interceptors are not applied to the return value of a producer method and the InterceptionFactory introduced in CDI 2.0 is not supported yet.
