NumberFormatException trying to connect to babashka-REPL

[MrGung]

This happens with babashka version 1.3.190 and I verified with 1.3.188 (which worked before updating to Cursive cursive-1.13.4-eap3-2023.3).

I downgraded to cursive 1.13.3-2023.3 - connecting to the REPL works there with the latest babashka version of 1.3.190.

Obviously - this is a problem with a superfluous newline in the string parsed as integer.
