Paul King closed GROOVY-7907.
-----------------------------
> Cannot assign value of type java.lang.Object with varargs, parameterized
> method and @CompileStatic
> --------------------------------------------------------------------------------------------------
>
> Key: GROOVY-7907
> URL: https://issues.apache.org/jira/browse/GROOVY-7907
> Project: Groovy
> Issue Type: Bug
> Components: Static compilation
> Affects Versions: 2.4.7
> Environment: Groovy 2.4.7 (tested also with 2.4.4)
> Reporter: Marcin Zajaczkowski
> Assignee: Paul King
> Priority: Minor
> Fix For: 2.4.8
>
>
> Static compilation fails when method is parameterized and there are varargs
> arguments which are not used in the call.
> {code}
> Error:(9, 23) Groovyc: [Static type checking] - Cannot assign value of type
> java.lang.Object to variable of type Ext.
> {code}
> Simple classes to reproduce the problem:
> {code}
> public class FooInJava { //needs to be in Java, a class in Groovy works fine
> <T> T create(Class<T> type, Object... args) { return null; }
> }
> class Ext {}
> @CompileStatic
> class FooMain {
> static void main(String[] args) {
> Ext create = new FooInJava().create(Ext) //casting is required to
> make compilation pass
> }
> }
> {code}
> It only occurs if a class with unfortunate method signature is written in
> Java and static compilation is enabled. Casting to the right type helps.
> Originally spotted with Gradle - `ExtensionContainer.create(...)`.
