Type mismatch problem when trying to get annotation from returnType of method (was issue 715)

[dholzenburg]

Hi,

I used your latest testcase in issue #715 and that worked fine. I made a minor modification and now it works with javac, but fails with j2objc.

Sorry to bother you again with this one ;-) This issue is not a blocker for me.

BTW: I like j2objc very much and I really appreciate your efforts. Besides this minor issue j2objc works very well. Thank you!

import java.lang.annotation.*;

@Target({ElementType.METHOD, ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
public @interface SomeAnnotation {

  String value() default "";
}

import java.lang.reflect.Method;

@SomeAnnotation("type")
public class SomeClass {

  public static void main(String... args) throws NoSuchMethodException {
    final Method method = SomeClass.class.getMethod("someMethod");

    //works
    System.out.println("annotation on method: " + method.getAnnotation(SomeAnnotation.class));

    //works
    System.out.println("1: annotation on return type: "
      + method.getReturnType().getAnnotation(SomeAnnotation.class));

    //fails
    final SomeAnnotation someAnnotation = method.getReturnType().getAnnotation(SomeAnnotation.class);
    System.out.println("2: annotation on return type: " + someAnnotation);
  }

  @SomeAnnotation("method")
  public SomeClass someMethod() {
    return null;
  }
}

Output:

$ javac SomeClass.java SomeAnnotation.java 
$ java SomeClass
annotation on method: @SomeAnnotation(value=method)
1: annotation on return type: @SomeAnnotation(value=type)
2: annotation on return type: @SomeAnnotation(value=type)
$ /usr/local/j2objc/2.1.1/j2objc SomeClass.java SomeAnnotation.java 
SomeClass.java:18: error: incompatible types: java.lang.annotation.Annotation cannot be converted to SomeAnnotation
    final SomeAnnotation someAnnotation = method.getReturnType().getAnnotation(SomeAnnotation.class);

Fixed in current source.
