Hi @mlchung Mandy, I've changed the offset to seperate load and return opcodes, which is more in-line with how other fields in `PrimitiveTypeInfo` are used. In addition, I specified that the `wrapperClassName` is an internal name for clarification. Would you mind review this again, and review #8800, which avoids eager class initialization for parameter types used by proxy?
