Double-slash typo in editor causes StringIndexOutOfBoundsException #3857
Description
CIDER 1.21.0-snapshot
nREPL 1.5.2
Clojure 1.12.4
Java 25.0.1+8-27
To trigger the error, it's enough to write something like this:
user//what
The two slashes do the magic.
Yes, it is "bad user input", caused by clumsy fingers or some other problem between chair and keyboard, but this seems like an overly drastic way of handling it (and the error is usually signalled twice):

This is a CIDER middleware error.
It may be a due to a bug, or perhaps simply to bad user input.
If you believe it's a bug, please submit an issue report via `M-x cider-report-bug`.
If these stacktraces are occurring frequently, consider using the
button(s) below to suppress these types of errors for the duration of
your current CIDER session. The stacktrace buffer will still be
generated, but it will "pop under" your current buffer instead of
"popping over". The button toggles this behavior.
