Java

With this release JavaProto no longer uses sun.misc.Unsafe as long as you are utilizing the standard generated code. You should no longer see warnings printed about sun.misc.Unsafe. If you see any issues, please let us know on https://github.com/protocolbuffers/protobuf/issues/20760

Note that the runtime itself still contains references to sun.misc.Unsafe in paths which are exclusively to support Lite generated code. Lite is emitted by a separate code generator which creates generated code optimized for mobile clientside contexts, especially alongside R8 optimizations. Android does not have a timeline to removing sun.misc.Unsafe, and we have found the performance regression too significant to consider removing these paths at this time. It is still TBD for how we can best navigate this mobile vs JVM split on this topic.
