Spring Boot jar launcher does not work in folders containing certain chars

[pashazadeh]

I have my microservices fat-jars in a folder name containing "#" in its name. It worked fine with Spring Boot 3.1.5 and 3.1.6, but now on Spring Boot 3.2.0 I got following error:

It was hard to determine the root of error, but now as a workaround I changed the folder names (removing "#" from their names).

By the way our OS is Redhat Linux.

Thanks for the report @pashazadeh. I think I've managed to fix this for 3.2.1.
