Eric Milles updated GROOVY-11094:
---------------------------------
Description:
I have the following program:
{code}
import java.util.*;
import java.util.function.*;
class Bar {
LinkedList<String> collect(Supplier<String> function) {
return null;
}
List<String> collect(String x, int y, int d) { return null; }
}
class Main {
static final void test() {
Bar x = null;
LinkedList<String> d = x.collect(() -> "fda");
}
}
{code}
h3. Actual behaviour
{code}
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
test.groovy: 14: [Static type checking] - Cannot assign value of type
java.util.List<java.lang.String> to variable of type
java.util.LinkedList<java.lang.String>
@ line 14, column 28.
LinkedList<String> d = x.collect(() -> "fda");
^
1 error
{code}
h3. Expected behaviour
Compile successfully
h3. Notes
Tested against master (commit: cac91791764b8f0b3338318248474412f89e3456)
