We have an issue with a minor Jira bug that sends the Last-Modified header on its batch.css and batch.js files as “Wed, 31 Dec 1969 23:59:59 GMT” which is 1 second before the beginning of Unix epoch time… and thus our Webseal proxy rejects these files.
No fix from Atlassian on the horizon so I have been searching through the source code for a way to patch this ourselves, but no luck so far. Tried patching the HttpResponseHeaders class manually setting the header like below in its methods, but no luck.
response.setDateHeader("Last-Modified", 1);
Maybe this is not even possible, or I am looking in the wrong place, or just doing it wrong. I have done some simple plugins and scripting but am no means a Java expert. Any guidance would be greatly appreciated as this issue has us stuck on 8.5! (Issue is still there in 8.20.1, which is the version I am looking to modify, and upgrade to, if we can fix this.)
