> In request or response header, some `Integer` fields(queueId, sysFlag, etc) are assigned by `java.lang.Integer#parseInt(java.lang.String)`. Is it more appropriate to use `java.lang.Integer#valueOf(java.lang.String)` to prevent auto-boxing? `valueOf()` will use `IntegerCache`, but the behavior of auto-boxing depends on the implementation of compiler. The java 8 compiler use Integer.valueOf(Integer) for auto-boxing, frequently requested values is caching. By the way, the rocketmq header objects should use primitive types, but I do not change this time. -- This is an automated message from the Apache Git Service.
