ADDITIONAL SYSTEM INFORMATION :
Manjaro Linux, OpenJDK Java 17.0.1 and 18 EA.

A DESCRIPTION OF THE PROBLEM :
Compiler rejects use of `Stream::toList` but not `Stream::collect(Collectors.toList())

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Save source code as StreamBug.java, execute `java StreamBug.java`

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
No output. (File compiles and runs.)
ACTUAL -
Compiler prints:

StreamBug.java:8: error: incompatible types: List<Class<CAP#1>> cannot be converted to List<Class<?>>
        List<Class<?>> output = input.stream().map(a -> a).toList();
                                                                 ^
  where CAP#1 is a fresh type-variable:
    CAP#1 extends Object from capture of ?
1 error
error: compilation failed

---------- BEGIN SOURCE ----------
import java.util.List;
import java.util.stream.Collectors;

public class StreamBug {
    public static void main(String... args) {
        List<Class<?>> input = List.of();
        List<Class<?>> output = input.stream().map(a -> a).toList();
        List<Class<?>> output2 = input.stream().map(a -> a).collect(Collectors.toList());
    }
}
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
use `collect(Collectors.toList())`

FREQUENCY : always
