when running the current openmrs master branch, which points to a call of Listener.loadBundledModules(servletContext); trying to load modules which are bundled with openmrs-core at startup.
I think we deleted the folder when we removed modules from openmrs-core.
I could
add the src/main/webapp/WEB-INF/bundledModules back with a .gitkeep file in it, so the warning disappears and the logic remains the same
remove the call to Listener.loadBundledModules(servletContext); since we do not bundle modules
