Using build 3.1 M5 candidate (I20040215-2300). Having following test case: Test.java: import e.Team; @Author(name={Team.DAVID, Team.JEROME}) @| // <-- Try to complete here: NPE public class Test { @Author(name=Team.PHILIPPE) void foo() {} @Author int t; } Author.java: import e.Team; public @interface Author { Team[] name() default Team.FREDERIC; } Team.java: package e; public enum Team { PHILIPPE, DAVID, JEROME, FREDERIC; } If you try to complete at caret position, then you get an Error Excuting Command dialog. Debug shows that there's a NPE in ResultCollector.accept(CompletionProposal) method due to name==null for CompletionProposal
Here's NPE stack trace: java.lang.NullPointerException at java.lang.String.<init>(String.java:166) at java.lang.String.valueOf(String.java:2145) at

Fixed and test added CompletionTest_1_5#test0087() CompletionOnAnnotationOfType name must not be an empty array
The NPE is gone, but the proposal should only be annotations. This is a separate issue reported in bug 89600. Verified in I20050330-0500
