Summary:

Even though the Key from the language pack have been updated with the latest accepted string from the website, it did not update the string.
It is not a problem for a language that is not bundled by default, but for a language bundled by default.

Steps to Reproduce:

1. Download JIRA Service Desk German Language pack ver 3.2.0-OD-03-001 from https://translations.atlassian.com/
2. Navigate to JIRA Administration > Add-ons > Manage Add-ons
3. Upload the downloaded JAR file with "Upload Add-on" feature
4. Change the Default Language to Deutsch
5. Navigate to a Service Desk project
6. Invite a Customer and wait for the notification

Expected Result:

• The notification will be using the latest string from the package:

  Hallo,
  
  <user> hat Sie zum Portal <portal-name> eingeladen!
  

Actual Result:

• The notification still using the bundled translation from JIRA Service Desk:

  Hallo,
  
  <user> hat dich zum Portal <portal-name> eingeladen!
  

Workaround

Install the plugin

• German JIRA Service Desk-3.2.0-OD-06-ms1-language-pack-de_DE-altered.jar
• Japanese JIRA Service Desk-3.2.0-OD-17-001-D20160623T024052-language-pack-ja_JP_altered.jar

Notes:

• All the string could be found by extracting the Language Pack and "jira-servicedesk-application" JAR files.
• The example above is using the language pack JIRA Service Desk-3.2.0-OD-03-001-language-pack-de_DE.jar sd-18n with key/string found as:

  sd.email.conversational.notification.agent.invite.customer.description={0} hat Sie zum Portal {1} eingeladen\!

• Comparing to the jira-servicedesk-application sd-18n for DE:

  sd.email.conversational.notification.agent.invite.customer.description={0} hat dich zum Portal {1} eingeladen\!
