Issue Summary

Jira Batched and non Batched notification emails show an empty value for custom fields using the name "Comment", even if this field is not empty.

Note about the bug

• It is replicable on 8.20.30 and 10.7.0 versions, so it is likely that all versions in between are impacted
• Versions lower than 8.20.30 might also be impacted
• The bug impacts both Jira Batched and Non Batched Notifications

Steps to Reproduce

• Create a new Single Line Text Custom Field called "Comment" and include it in a project:
  
• Create a new issue in this project
• Add some value to the "Comment" Custom Field
  
• Wait for the notification to be sent

Expected Results

The value added to the "Comment" Custom Field should be shown in the notification email.

Actual Results

The "Comment" Custom Field is shown with a "null" value:

Note

Note that, when Notification Batching is OFF, the same issue happens, except that no value at all is shown for that field, instead of "null":

Workaround

Change the name of the custom field to something else than "Comment".
