@PublicApi can expect
that programs compiled against a given version will remain binary compatible with later versions of the
@PublicApi as per each product's API policy as long as the client does not implement/extend
@PublicApi interfaces or classes (refer to each product's API policy for the exact
guarantee---usually binary compatibility is guaranteed at least across minor versions).
@PublicApiinterfaces and classes are not designed to be implemented or extended by clients, we may perform certain types of binary-incompatible changes to these classes and interfaces, but these will not affect well-behaved clients that do not extend/implement these types (in general, only classes and interfaces annotated with
@PublicSpiare safe to extend/implement).
Objects of this class contains three fields that identify a user in the JIRA database: id, key, username.
All three fields are always not null.
