Summary: X-link: https://github.com/facebook/react-native/pull/39402 Pull Request resolved: https://github.com/facebook/yoga/pull/1377 To avoid keeping a per-node mapping on native Yoga nodes to Java nodes, a per-layout context was added, to be able to pass information from the start of the layout, to measure functions, log functions, etc. The way this was done was super invasive, and added quite a few private APIs used only by the JNI functions. This change removes the context-using functions from the JNI bindings in favor of it managing its own context. Next diff removes all the cruft.
