Problem Description: This is related to https://tracker.adobe.com/#/view/CF-4204404 but I'm creating another ticket since the repro case is a little different here. In ColdBox, we use on-the-fly CF mappings for every module that is loaded, but we've had so many issues related to these CF mappings "disappearing" during requests. I have nailed down a repro case that does not use ColdBox, demonstrating the issue. Basically, on-the-fly CF mappings will simply disappear as soon as the server gets another HTTP request while the first HTTP request is running. Calling getApplicationMetadata() prior to trying to using the mapping will make it magically reappear. There is one caveat-- this behavior only happens if there is at least one "this.mappings" defined in the Application.cfc. This issue causes very hard to track errors in ColdBox where mappings will simply not be found, often times during reinitting the framework. An HTTP request's CF mappings should not be affected by another HTTP request coming in. Steps to Reproduce: Unzip the attached file and run "server start" in the folder in CommandBox. This will spin up an Adobe 2018 server. The index.cfm will automatically load and you can read the output on the screen and cross reference that to the code to see what is happening. Actual Result: Unrelated HTTP requests delete CF mappings on running requests. Expected Result: Unrelated HTTP requests should not delete CF mappings on running requests. Any Workarounds: Call getApplicationMetadata() EVERY SINGLE TIME you use a CF Mapping, which in reality only narrows the race condition window, it doesn't eliminate it. Another workaround is to create this.mappings for every single module, which defeats the purpose of ColdBox adding them for you.
