Description

The annotation @GroovyASTTransformationClass marks another annotation as an AST Transformation. The annotation has a required parameter, a String[]. The parameters stores the fully qualified class name that will be invoked during the transformation phases.

As a convenience, the parameter type should be Class[] instead of String[]. It allows programmers to specify a class not a String that represents a class.

We cannot remove String[] because that would break backwards compatibility. We could add a 2nd parameter and then require 1 (and only one) of the two parameters to be specified.
