@enum fails under @lends with NPE?

I am seeing NullPointerExceptions when I do a @lends when extending a class with static members. A workaround I found to avoid the NPE was to make the enum a top level type (not a static class member) or append the @enum to the class with a simple assignment rather than extends/@lends.

I see the NPE on the current version of the CLI compiler at http://dl.google.com/closure-compiler/compiler-latest.zip and on the closure compiler appspot app. Here's a link where you can see the NPE in action:
