[jira] [Created] (GROOVY-9798) Internal compiler error when using
constructor as Function
Christopher Smith created GROOVY-9798:
-----------------------------------------
Summary: 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
(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}

{code}
This same code appears to compile correctly if I explicitly instruct {{.map(GnomeDto::new as Function)}}.
