>                 Key: GROOVY-8722
>                 URL: https://issues.apache.org/jira/browse/GROOVY-8722
>             Project: Groovy
>          Issue Type: Bug
>          Components: Compiler, Documentation
>    Affects Versions: 2.4.15, 2.5.1
>            Reporter: Dmytro Buryak
>            Assignee: Paul King
>            Priority: Major
>              Labels: breaking, documentation
>             Fix For: 2.5.2
>

> When using the {{final}} modifier in a trait non-abstract method signature, then:
>  * compiler successfully compiles trait and class that implements it
>  * final method of trait may be overridden in class that implements trait
>  * if class implements trait and doesn't override trait final method, then this method
is available as non-final method in class
>  * documentation says absolutely nothing about this
> In other words, {{final}} modifier is ignored in trait methods: code works the same with
or without it. Even if this behavior is expected, there's nothing about it in the documentation.
> Here's simple example gradle groovy project to demonstrate the issue: https://github.com/dburyak/groovy-bug-trait-final
