9.23.0 Improvements and Fixes

What's fixed?

• Fixed filename sanitization issues for .eml/.msg attachments

• Handling some quirky mail server connection errors

• Eliminated various entity and template loading/rendering errors caused by deficiencies in Velocity allowlist

• Got rid of page loading errors introduced by breaking Java security implementation changes upon Java runtime upgrades

• Other improvements and fixes

When the underlying Java runtime of the hosting system (the JRE used to run the Jira DC server) undergoes a major upgrade (especially when switching to Java 17+), some security features may automatically change in the background, effectively disallowing particular algorithms (e.g. those used for secure random number generation and data encryption).

This may render your previously stored, encrypted passwords and secrets unusable, as they cannot be decrypted with the newly employed algorithm anymore. As a consequence, certain features - like mailbox access and thus email processing and sending - may entirely stop working in the background.

To restore the operating state of the affected features of the Email This Issue application, these passwords and secrets must be entered and saved on the respective admin configuration pages again. This app release contains fixes to make loading of these configuration pages possible depsite of possible decryption errors. However, the restoration process shall be done manually for each and every impacted entity.
