We are encountering an issue with image rendering after upgrading to Jira 10.x.x from Jira 9.x.x when using the ARNR app.
In Jira 9.x.x, all images are rendered successfully, for example:
Working URL (Jira 9):
http://localhost:2990/jira/releasenotes/ARNImageAction!DownloadImage.jspa?projectId=10001&templateId=18&image=image_2.jpeg
However, in Jira 10.x.x, the same functionality fails when attempting to render images using a similar URL format:
Non-Working URL (Jira 10):
http://localhost:2990/jira/releasenotes/ARNImageAction!DownloadImage.jspa?projectId=10001&templateId=13&image=image_1.png
We have implemented image downloading through the JiraWebActionSupport class, and the ARNR app uses these URLs to render images.

Observations:
1)If the URL uses HTTP, the images fail to render in Jira 10.x.x.
2)The images render successfully if the URL is updated to use HTTPS.

Questions:

  1. Has there been a change in Jira 10.x.x related to handling HTTP URLs or a change in the way JiraWebActionSupport processes URLs for resources like images?
  2. Is there a new configuration or approach required to ensure compatibility for HTTP URLs in Jira 10.x.x?
