Is there any way to change the "creator" system field using the JIRA JAVA API. The background: the user should be able to create an issue which should be visible as anonymous within the system. So the reporter field can be easily changed during creation to some technical user called "anonymous", but still the "creator" field is set to the current user, who created the issue and this information is visible in the change history.
So one approach would be to change the creator within a post-function, e.g. script-runner, but how?
