Issue Summary

Jira Data Center 8.14.0 introduces this new functionality, so that e-mail templates are stored at Jira's Shared Home folder.

On environments using Windows, the path to the Shared home will be specified like \\path\to\shared_home and Jira tries to complete the path to the e-mail templates using '/' instead, so it is unable to find the files there.

Steps to Reproduce

1. Install Jira Data Center 8.14.0
2. Create an e-mail subscription for a filter
3. Wait until it's triggered

Expected Results

Jira will successfully send the subscription notification

Actual Results

Jira will send the notification with a "Could not locate resource" text.

At the application logs, Jira will throw a warning stating that the required template was not found:

com.atlassian.cache.CacheException: java.lang.RuntimeException: Couldn't load template! templateFile: templates/email/subject/filtersubscription.vm

Workaround

Disable new functionality:

1. Edit the file <JIRA_INSTALLATION_FOLDER>/atlassian-jira/WEB-INF/classes/jira-features.properties
2. Look for the setting called com.atlassian.jira.email.templates.readFromJiraHome and set it to false, as shown below:

   com.atlassian.jira.email.templates.readFromJiraHome=false
   

3. Save the change made to this file
4. Restart Jira
5. Jira will use bundled templates instead of custom ones from <Shared_Home>
