Affects Version/s: None
Fix Version/s: 2.0-pr
We would like to explore providing APIs for making common modifications to headers that are currently defined as system headers. Exmaples include:
1) No way to change outgoing message's record-route. For instance to add a parameter needed by a downstream device.
2) JSR 289 states that display name in Contact Header can not be modified. There is no good reason to enforce this restriction and most app developers want control over the display name.
3) In general there is no way to add parameters to system headers which is very common.
