I have successfully created application link between JIRA and fisheye using OAuth(both incoming and outgoing).
JIRA version 6.3.3 fisheye version 3.6.3
1.Application link between JIRA and Fisheye/Crucible Working fine.
2.Permissions for View Development Tools to include the necessary users to view source and review tab on View issue page has assigned.
3. enabled the Development Integration Plugin and all of it's module
4.Fisheye plugin's all modules enabled.
Also able to see development panel but Source and Review tab does not appear on View Issue page in JIRA.
Resolution:
1. Restart JIRA while leaving the other system still running
2. Delete and recreate the application link
3.Ensure the FQDN(Fully Qualified Domain Name) in SSL certificate matches JIRA and Fisheye/Crucible hostnames.
It worked for short time and tabs suddenly disappeared.
