Description

I have the following program

import java.lang.annotation.*;
import java.util.function.*;

@Target(ElementType.TYPE_USE)
@interface Nullable {}

class Test {
  public static void main() {
    IntUnaryOperator x = (@Nullable Integer y) -> 1;
  }
} 

Actual behavior

The compiler crashes

>>> a serious error occurred: BUG! exception in phase 'class generation' in source unit 'test.groovy' Adding type annotation @Nullable to non-redirect node: int
>>> stacktrace:
BUG! exception in phase 'class generation' in source unit 'test.groovy' Adding type annotation @Nullable to non-redirect node: int
