Concurrent edit saves changes to the history

Issue Summary

When having edit in an issue being done at the same time, Jira is performing the first change and then recording the second change, when in fact it should perform both changes or not record the second change due to corruption chances.

Steps to Reproduce

1. Create a New Project and Issue in a Jira project.
2. Have two users perform changes in this issue workflow (issue type change, transition the issue, etc).
3. Make users save the changes at the same time.
4. Observe the issue History

Expected Results

Both changes were applied or one of them is not applied.

Actual Results

One of the changes is applied and the next one is recorded in the issue history.

Workaround

Perform the changes one user at a time, or perform the changes stored in the issue history.
