Description

In groovy 2.4.0-rc-2 all was ok, but now I have an error in 2.4.0. I'm not sure if is an exception or maybe there was some bad code before. Exception raises, when in a gradle task, I convert a class that have an AST to javascript with grooscript. That conversion process compile the file. In tests I don't get the error, all is ok .The code fails here:

private addDrawMethod(ClassNode classNode) {
        classNode.addMethod('draw', Modifier.PUBLIC, null, Parameter.EMPTY_ARRAY,
                ClassNode.EMPTY_ARRAY, new AstBuilder().buildFromCode {
            this.render()
            gQuery.attachMethodsToDomEvents(this)
        }[0])
    }

And the error is:

General error during semantic analysis: AstBuilder.build(CompilePhase, boolean, Closure):List<ASTNode> should never be called at runtime.
  Are you sure you are using it correctly?

java.lang.IllegalStateException: AstBuilder.build(CompilePhase, boolean, Closure):List<ASTNode> should never be called at runtime.
