Description

Trying to use the `groovy.transform.etc` for the first time. When I run it, all works well until it gets to `org.codehaus.groovy.runtime.DefaultGroovyMethods.java`

There are a few problems with how the `public static <T> T[] plug(T[] left, xxx right)` method. Where xxx is T[], Iterable<T> right, or Collection<T> right.

In all of these cases, you just need to change the `return (T[]) plus(...).toArray();` to `return (T[]) plus((Collection<T>)...).toArray();

Problem solved.
