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.
