Users, who try to avoid null variable, can replace null by empty array to build header to be a kind of "flag". The ```RecordHeader#value()``` may be never called (as users only want to check existence of header) and so the receive buffer can't be released by GC until users get rid of ```Header```. ### Committer Checklist (excluded from commit message) - [ ] Verify design and implementation - [ ] Verify test coverage and CI build status - [ ] Verify documentation (including upgrade notes) ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
