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.
