We can use long type internally representing bytes for convenience of calculations, and MemorySize for arguments and return values of the methods. This probably also involves replacing int/long type memory sizes with MemorySize for MemoryManager. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
