      Issue Summary

      This is reproducible on Data Center: Yes

      Steps to Reproduce

      • Browse to General Configuration > Global Templates and Blueprints > Add global page template
      • Add any variable to the page and an empty HTML Macro.
      • Save the template, and use it to create a new page.

      Expected Results

      You will see the editor and be able to use the template and create a new page.

      Actual Results

      You are brought to an error page, "Oops - an error has occurred". There is no stack trace on this page, but there is in the logs.

      The below exception is thrown in the atlassian-confluence.log file:

	at org.apache.velocity.runtime.parser.node.ASTReference.execute(ASTReference.java:262)

      Workaround

      Currently there is no known workaround for this behavior, but adding any content to the html macro resolves the issue.
