We are using Jira 4.4.4 on-premise server which work on Java 6, currently nearly all email service provider stopped support of TLS 1.0 & TLS 1.1 and Jira 4.4.4 doesn't support TLS 1.2 hence we are unable to receive email notification being sent from Jira server related to projects and tickets. Is there any way to enable the TLS 1.2 support on Jira 4.4.4?
If we update Java version to 8, Is Jira 4.4.4 compatible with it?
Please advise...
