csvImporter return blank screen for detailed logs after Jira 9.5+

Problem

csvImporter return blank screen for detailed logs after Jira 9.5+.
No errors in logs could indicate a Log4J issue, as issue is reproducible only in Jira versions using Log4j2.

Environment

Jira Server/DC 9.5+ over Windows, any database

Steps to Reproduce

1. Go to Jira import wizard > CSV and perform an import
2. After the import is complete, click on "download a detailed log" of this import

Expected Results

• A new window will open with <Jira_Base_URL>/rest/jira-importers-plugin/1.0/importer/com.atlassian.jira.plugins.jira-importers-plugin:csvImporter/log and show the detailed log for the import

Actual Results

• It opens a blank window for <Jira_Base_URL>/rest/jira-importers-plugin/1.0/importer/com.atlassian.jira.plugins.jira-importers-plugin:csvImporter/log, no content is showed.

Workaround

No workaround available yet.

Notes

Issue is reproducible in Windows servers running Jira 9.5+, with any database.
Jira 9.5+ over Linux present no problem, it returns expected results.
