Cannt compile this sample class with Eclipse in JDK 1.5 mode.
I successfully compiled and run it under JDK1.5.0:

C:\eclipse\workspace\annotations\src>"C:\Program
Files\Java\jdk1.5.0\bin\javac.exe" -source 1.5 test/*.java

C:\eclipse\workspace\annotations\src>"C:\Program
Files\Java\jdk1.5.0\bin\java.exe" -cp . test/AnnotationsTest
true

Annotations support is very uncomplete.

Error messages:

"@Retention": "Return type for the method is missing"
"isAnnotationPresent": "The method isAnnotationPresent(Class<? extends
Annotation>) in the type 
 Class<AnnotationsTest.A> is not applicable for the arguments 
 (Class<AnnotationsTest.TestAnnotation>)"

== Sample code ==
package test;

import java.lang.annotation.ElementType;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
import java.lang.annotation.Retention;

public class AnnotationsTest {

  @Retention(RetentionPolicy.RUNTIME) @Target(ElementType.TYPE) @interface
TestAnnotation {

    String testAttribute();

  }
  @TestAnnotation(testAttribute = "test") class A {
  }

  public static void main(String[] args) {
    System.out.println(A.class.isAnnotationPresent(TestAnnotation.class));
  }

}
