-------------------------------
Resolution: Cannot Reproduce
> Internal compiler error when using constructor as Function
> ----------------------------------------------------------
>
> Key: GROOVY-9798
> URL: https://issues.apache.org/jira/browse/GROOVY-9798
> Project: Groovy
> Issue Type: Bug
> Components: Compiler, Static compilation
> Affects Versions: 3.0.6
> Reporter: Christopher Smith
> Priority: Major
>
> (Background that I don't think is relevant, but in case: I have written some
> extension methods in plain Java and am pulling them in as Maven dependencies.
> The STC does correctly identify these methods and expect appropriate
> parameters.)
> When invoking a method that takes a {{Function<? super A, R> mapper}}, I am
> trying to pass a constructor method reference as the parameter:
> {{.map(GnomeDto::new)}}. This appears to get past canonicalization happily
> enough, but the actual class generation throws an internal compiler error:
> {code}
> [ERROR] java.lang.ArrayIndexOutOfBoundsException: Internal compiler error
> while compiling
> /home/christopher/gnomes/src/main/groovy/com/example/gnomes/GnomeController.groovy[ERROR]
> Method:
