Marcin Zajaczkowski created GROOVY-7907:
-------------------------------------------
Summary: Cannot assign value of type java.lang.Object with
varargs, perameterized 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
Priority: Minor
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 {
<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(...)`.
