Summary:
@public
In the JNI portion of CSSLayout, there's a subtle bug where we were caching the jmethodid of the 'measure' of the first object that had measure called on it. However, if that class had overriden measure, then the jmethodid would be specific to that subclass's implementation and would not work for other classes. Conversely, if a regular CSSNode had been called first, then the super method would be called on the subclass instead of the proper overriden method.
Since there's not really a reason to overriden measure anyway (since you can just provide a different measure function), it's safest to just mark it final and explicitly cache the appropriate methodid
