Description Paul Cowan

Build ID: I20080207-1530

Steps To Reproduce:
1. Create a new package, 'example'
2. Create a java file, 'example/package-info.java'
3. Include the following contents
   @Deprecated
   @Deprecated
   package example;


Expected result: this should be flagged as an error. On a class, this would (correctly) cause 'Duplicate annotation @Deprecated'; on package-info, however, Eclipse ignores it. However on trying to access the package annotations in the Sun JVM at runtime, you'll get:

java.lang.annotation.AnnotationFormatError: Duplicate annotation for class: interface java.lang.Deprecated: @java.lang.Deprecated()
	at sun.reflect.annotation.AnnotationParser.parseAnnotations2(AnnotationParser.java:75)
	at sun.reflect.annotation.AnnotationParser.parseAnnotations(AnnotationParser.java:52)
	at java.lang.Class.initAnnotationsIfNecessary(Class.java:3072)
	at java.lang.Class.getAnnotation(Class.java:3029)
	at java.lang.Class.isAnnotationPresent(Class.java:3042)
	at java.lang.Package.isAnnotationPresent(Package.java:376)


etc.
