AnnotationProcessor6 shows warning when isn't used

[Jim Jake <ma...@mail.ru.INVALID>]

Hi,

despite not using any enhancement at all, I still see this warning 
during maven build:

WARNING: Supported source version 'RELEASE_6' from annotation processor 
'org.apache.openjpa.persistence.meta.AnnotationProcessor6' less than 
-source '1.7'

I do not use neither openjpa-maven-plugin nor an OpenJPA javaagent. I 
just have "openejb-core" artifact as one of my test dependencies.

Surely there is no reason for the annotation processor to be called by 
Maven?

Is this warning a sign of some kind of implicit enhancement happening, 
or does it mean something else?


Best regards,

Jim Jake
