In the following example the method 'f' completes without exceptions, and the method 'f' (which differs only in the order of the components of the bounds of its type parameter) fails with a CCE.

This seems similar to JDK-8011392. Should javac be emitting additional checkcasts for the components of the type parameters' bounds, or only for the erased type?

```
import java.util.*;

class T {
  public static void main(String[] args) {
    f();
    g(); // CCE
  }

  static <T extends List<?> & Runnable> void f() {
    Runnable r = (T) new ArrayList<>();
  }

  static <T extends Runnable & List<?>> void g() {
    Runnable r = (T) new ArrayList<>();
  }
}
```

$ javap T
...
  static <T extends java.util.List<?> & java.lang.Runnable> void f();
    descriptor: ()V

         7: astore_0
