Shil Sinha commented on GROOVY-7688:
------------------------------------
As John mentioned, this is a more general case of the bug in GROOVY-7656.
Receivers for spread safe method calls are visited twice - once as a receiver
of the spread safe method call, and once as a receiver of the iterator of the
resulting for loop.
> Using spread operator on function with compile static results in two calls to
> function

> Key: GROOVY-7688
> URL: https://issues.apache.org/jira/browse/GROOVY-7688
> Project: Groovy
> Issue Type: Bug
> Affects Versions: 2.4.5
> Reporter: Michał Lewandowski
> Priority: Minor
>
> Method *heavyOperation()* will be called twice. If we remove @CompileStatic,
> problem is solved.
> {noformat}
> @CompileStatic
> List<String> invokeCompileStatic(Service service){
> service.heavyOperation()*.toString()
> }
> {noformat}
> A test which confirms it, can be found in [my
> Gist|https://gist.github.com/mlevvy/948e13414be360a20212]
