09:39 PM Ruby Bug #22007: Inconsistent type checking on rescue

This path avoids the sources getting wiped out during `mvn clean`,

04:26 PM Ruby Feature #21960: Improve #backtrace to not confuse terminals

Is there any de-facto standard syntax that editors might interpret as a file + line combination? It would be extra great to make such stack trace output clickable AND go to the right line.
