This query detects cases where the development mode is enabled for a
struts configuration. I can't find a CVE per se but, at present, [Github's fuzzy search](https://github.com/search?q=%3Cconstant+name%3D%22struts.devMode%22+value%3D%22true%22+%2F%3E+language%3Axml&type=Code) returns more
than 44000 results. Some of them look like they are classroom projects,
so they may be ineligible for a CVE. But we should be flagging them
anyways as setting the development on in a production system is a very
bad practice and can often lead to remote code execution.
So these should be fixed anyways.
