~~JDK-8233164~~ fixed a problem where the type of a CheckCastPP was updated during EA (because the allocation was found to be non-escaping) but a Load and a subsequent CastPP user were not updated. This lead to incorrect re-wiring of memory edges.

More such problems potentially exist, see discussion in this thread:
