        CodeCache::nmethods_do() iterates over all existing methods. Among those might be some which are not fully constructed yet. Thus, the _method field might be zero or (even worse) contain a random value. This effect was observed previously while implementing CodeHeap State Analytics.

        I would expect this bug to exist in previous versions as well.
