Cannot link a JIRA issue to a Confluence page (over SSL) when the Page Title contains Comma, Colon, and/or other Special Characters

Summary

It is not possible from a JIRA issue to create a link to a Confluence page if the page title contains a special character e.g. "," (comma) or ":" (colon).

When trying to create the link, JIRA displays the warning message "No Confluence page found with the given URL."

 This is different from JRASERVER-44784 in terms of the error thrown.

Steps to reproduce

1. Configure JIRA and Confluence to run over SSL and create an Applinks between them
2. Create a Confluence Page with a comma, colon, and/or other special characters in its Title e.g. "Hello, this is a page" or "Hello: This is a page"
3. From JIRA View Issue screen -> More -> Link -> Confluence Page -> search for the above page -> Link

Expected behavior

The Page can be linked without problem

Actual behavior

The Page can't be linked and JIRA displays the message: No Confluence page found with the given URL.

From JIRA log, the following error is seen:

2017-04-17 22:31:18,674 http-nio-2768-exec-5 ERROR admin 1351x2439x1 1loq84v 192.168.1.100,192.168.1.100 /secure/LinkConfluencePage.jspa [c.a.j.p.link.confluence.LinkConfluencePage] Invalid response from getting the pageId: OAuth authentication failed: signature_invalid

From Confluence log, the following error is seen:

 From the browser's F12 developer tools, the status code is actually 200.

Note

If JIRA and Confluence run over HTTP, the same Page (with special characters in its title) can be linked without problem.

Workaround

• Temporarily remove the Special Character from the Page Title before linking, then edit the Page Title to add it back
• Use JIRA Macros to mention the JIRA Issue in the Confluence Page
• Use the page link that contains its page ID instead (manually):
  • Get the link by clicking Options (...) -> Page Information -> change the URL from ...viewinfo.action... to ...viewpage.action...
