Repeated ClassCastException Crahses

With 1.9 moving into a bug fixing phase I decided to try to load a backup of my 1.8.7 world in the latest snapshot. While doing this I have been getting repeated (over 20) crashes from a ClassCastException: "ahw cannot be cast to ahn", and the Stacktrace is basically gibberish to me. I have included the crash reports that had different entities being ticked when the crash occurred. They were a Witch, Villager and an Enderman; although the majority of the crashes were a Villager. I don't know if it is related but I will mention that in all cases the entity being ticked had a NullPointerException under its "Entity's Vehicle:" section. I hope this gets resolved otherwise I'll have to start a new world and lose all I've made if I want to play with 1.9 features. 😞

Ah, sorry about that duplicate. Looks like the search didn't pick up the other issues because they are all one word ("java.lang.ClassCastException:") and were all linked to various other possible causes. Glad to see that people know about this and that a fix is in the next version. Thanks!

For the future: search for the class names - if the issue is popular you'll probably get at least one hit.
