mgroovy updated GROOVY-9968:
----------------------------
Description:
*Problem*
Trying to build the sample test code below fails with:
{code:java}
Groovyc: [Static type checking] - No such property: name for class:
java.lang.Object
Groovyc: Expected parameter of type java.lang.Object but got
simple.groovy.bugs.groovy3.gb_2021_03_05.iterable_t_extends.Foo
Groovyc: [Static type checking] - No such property: name for class:
java.lang.Object
{code}
If we do not explicitly give the member type of the IterableTExtendsFoo
iterable, Groovy assumes that the type is Object, even though it has been
defined as being a subclass of Foo in the definition of IterableTExtendsFoo<T
extends Foo>.
*Expected*
* Code should compile.
* If Groovy could not deduce that IterableTExtendsFoo has been initialized
with a List<T extends Foo>, then it should reject the line where the
IterableTExtendsFoo ctor is called.
* Note: Works as expected in Groovy 2.5.x (at least up to 2.5.14)
*Sample Code*
{code:java}
import groovy.transform.TypeChecked
import org.junit.Ignore
import org.junit.Test
@TypeChecked
class Groovy3_Iterable_T_extends_Bug {
@Test
@Ignore
void 'Groovy 3-0-7 Members of Iterable T extends Foo are Foo'() {
// Compiler should reject the following line if the ctor arg
would not of type List<T extends Foo>
final iterableTExtendsFoo = new IterableTExtendsFoo([new
Foo('Sli'),new Foo('Msha'),new Foo('Dy'),])
//final iterableTExtendsFoo = new IterableTExtendsFoo<Foo>([new
Foo('Sli'),new Foo('Msha'),new Foo('Dy'),]) // This works
println iterableTExtendsFoo.collect { "Hi, my name is:
$it.name" }
println iterableTExtendsFoo.collect { Foo f -> "name=$f.name" }
}
}
