I think your best start is the ChangeHistoryManager, which you can inject or get by ComponentAccessor.getChangeHistoryManager()

https://docs.atlassian.com/software/jira/docs/api/7.0.5/com/atlassian/jira/issue/changehistory/ChangeHistoryManager.html

As far as I recall, you get a List of ChangeHistoryItem where you can extract all relevant Information (getField, getFroms, getTos, etc.). The basic idea would be to look for a change from an empty value to something longer.

Best regards,
