TCK is missing tests for standalone Asynchronous

See also https://github.com/eclipse/microprofile-fault-tolerance/blob/master/tck/src/main/java/org/eclipse/microprofile/fault/tolerance/tck/AsynchronousInvocation.java

The TCK also misses a test that FaultToleranceDefinitionException is thrown if a method annotated with @Asynchronous does not return Future.

Is it supposed to be a constraint? I honestly had no idea.

[antoinesd]

In section 4.1, the spec states:

The method annotated with @Asynchronous must return a Future, otherwise, FaultToleranceDefinitionException occurs

So it looks like a constraint.

But I can also apply @Asynchronous to a class. I can also add @Bulkhead to the mix and then what's expected?

[mkouba]

I would guess @Asynchronous declared on a class => all methods must return Future.

[Emily-Jiang]

yes @mkouba !

[Emily-Jiang]

please feel free to do a PR to add tests @mkouba !

[Emily-Jiang]

@antoinesd @mkouba pls help with adding more tests.

[antoinesd]

Taking it

Just a though, but wouldn't a standalone @asynchronous annotation more belong in a concurrency spec?
