Comment 8 Svata Dedic 2012-09-07 14:37:58 UTC

getNestedItems() is annotated as @NonNull. I tried to inspect all implementations in the standard distribution, found 1 place where the impl MAY return null - sometimes. It's in HTML, and occurs when the parent item is not found in the newly parsed text for some reason. This may occur when e.g. outer elements are passed, or some unclosed element appears prior to the expanded item.

Passing proposed diff for evaluation to HTML maintainer.
