Issue Summary

This is reproducible on Data Center: yes

This affects all version of Confluence.

When a user adds the code macro to a page in Confluence DC page, it imports the JavaScript in shCore.js, which overloads the

• RegExp.prototype.apply
• RegExp.prototype.call
• RegExp.prototype.exec
• RegExp.prototype.test
• String.prototype.match
• String.prototype.replace
• String.prototype.split

functions (at a minimum). This causes issues with any other code that uses these functions as they are not equivalent to the default functions.

This is specific to the confluence-newcode-macro-plugin.

Steps to Reproduce

1. Create a page in Confluence Server DC
2. Add a code macro, this will bring in the minified JavaScript from shCore.js
3. Add another macro that has a dependency on one of the overloaded functions

Expected Results

The page loads without issue.

Actual Results

The page may become unresponsive, or the second macro fails to run.

Workaround

Remove the code macro from pages that have other macros that rely on correct functioning of RegExp
