      FULL PRODUCT VERSION :
      java version "1.7.0_01"
      Java(TM) SE Runtime Environment (build 1.7.0_01-b08)
      Java HotSpot(TM) 64-Bit Server VM (build 21.1-b02, mixed mode)

      FULL OS VERSION :
      Linux 10.04

      A DESCRIPTION OF THE PROBLEM :
      When you create an annotation with a string value inside and assign it to e.g. a method, and you use as value a deprecated static final string, the compiler throws a nullpointer-exception. Note that the deprecated string MUST be in another class. When the deprecated string is defined where the annotation is applied, it will compile.

      THE PROBLEM WAS REPRODUCIBLE WITH -Xint FLAG: Did not try

      THE PROBLEM WAS REPRODUCIBLE WITH -server FLAG: Did not try

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Class 1:

      public class LocalNames {
          @Deprecated
          final public static String WHATEVER = "whatever";
      }

      Class 2:
      public @interface Test {
          public String value() default "";
      }

      Class 3:
      public class JavaApplication14 {
          @Test(LocalNames.WHATEVER)
          public static void main(String[] args) {
              // TODO code application logic here
          }
      }

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      Should compile
      ERROR MESSAGES/STACK TRACES THAT OCCUR :
      An exception has occurred in the compiler (1.7.0_01). Please file a bug at the Java Developer Connection (http://java.sun.com/webapps/bugreport) after checking the Bug Parade for duplicates. Include your program and the following diagnostic in your report. Thank you.
