@chris_johnson suggestions for improvements are always welcome. Just file some ticket about this and we’ll take a look.

Just keep in mind that errors during REPL boot time are a bit different as not everything is working properly at this point.

can I make the file readonly when cider debugger is active?

It’s not like “there was an error during system startup; I won’t tell you what it is, but here is the name of a Java exception class that got thrown with no other context” is a problem unique to Cider; that is one of the small prices we all gladly pay to be in the Clojure ecosystem hehe
