Currently, when there are errors in Jelly scripts, the error messages cannot always be internationalised. Support for rendering translated messages is available in the service tier classes (e.g. ProjectRoleService and ProjectComponentService) but not all Jelly tag errors have corresponding service tier methods (e.g. jelly tag DeleteProjectRole confirm="true" attribute). A Jira AuthenticationContext could be injected into the EmbededJellyContext (sic) as long as that class became managed by the DI container.
