+// A note about how strings are handled. This code used to just store a String
+// in the Message. This had two issues:
+//
+//  1. It wouldn't roundtrip byte arrays that were not vaid UTF-8 encoded
+//     strings, but rather fields that were raw bytes incorrectly marked
+//     as strings in the proto file. This is common because in the proto1
+//     syntax, string was the way to indicate bytes and C++ engineers can
+//     easily make this mistake without affecting the C++ API. By converting to
+//     strings immediately, some java code might corrupt these byte arrays as
+//     it passes through a java server even if the field was never accessed by
+//     application code.
+//
+//  2. There's a performance hit to converting between bytes and strings and
+//     it many cases, the field is never even read by the application code. This
+//     avoids unnecessary conversions in the common use cases.
+//
+// So now, the field for String is maintained as an Object reference which can
+// either store a String or a ByteString. The code uses an instanceof check
+// to see which one it has and converts to the other one if needed. It remembers
+// the last value requested (in a thread safe manner) as this is most likely
+// the one needed next. The thread safety is such that if two threads both
+// convert the field because the changes made by each thread were not visible to
+// the other, they may cause a conversion to happen more times than would
+// otherwise be necessary. This was deemed better than adding synchronization
+// overhead. It will not cause any corruption issues or affect the behavior of
+// the API. The instanceof check is also highly optimized in the JVM and we
+// decided it was better to reduce the memory overhead by not having two
+// separate fields but rather use dynamic type checking.
+//
+// For single fields, the logic for this is done inside the generated code. For
+// repeated fields, the logic is done in LazyStringArrayList and
+// UnmodifiableLazyStringList.
