// A note about how strings are handled. In the SPEED and CODE_SIZE runtimes,
// strings are not stored as java.lang.String in the Message because of 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.
//
// In the LITE_RUNTIME, we store strings as java.lang.String because we assume
// that the users of this runtime are not subject to proto1 constraints and are
// running code on devices that are user facing. That is, the developers are
// properly incentivized to only fetch the data they need to read and wish to
// reduce the number of allocations incurred when running on a user's device.
// TODO(dweis): Consider dropping all of the *Bytes() methods. They really
// shouldn't be necessary or used on devices.
