To recreate the issue just unzip the application and run grails console. It's 100% reproducible.

It's the @TupleConstructor part of @Canonical that triggers the problem, @EqualsAndHashcode and @ToString work as expected.

I get the same error message with a constructor with default parameter in a domain class, e.g.:

public Deadline(Date deadline = new Date()) { this.deadline = deadline }

Also it's important to notice that @TupleConstructor doesn't create any constructor if one already exists in the class.

@Cedric that seems to indicate to me that my transformation is running after @TupleConstructor so in that case do local transforms run before global ones?
