Step Over taking forever on Spring Boot Application

I'm trying VSCode with Java for the first time as an option for Eclipse. Configured the environment pretty easily (Java Extension Pack, Spring Boot 4 EP, Lombok) and could run my project.

In order to test debugging I enabled a breakpoint on the first line of my Controller. It basically calls a injected bean service method and LOTS of stuff happen inside it, finally throwing an exception. Here VSCode behaves in 2 very different ways:

1. If after hitting the breakpoint I resume (F5) the execution, it finishes processing almost immediately (0.3s)
2. If after hitting the breakpoint I do a step over (F10), it takes forever (like 207s)

During this 3 minutes I pressed pause sometimes, and VSCode stops in all kinds of library code (JPA, Logback, Spring, etc.), so I wonder if this can be related to this closed issue? Our project has very "fat" jar with lots of dependencies, but I don't know how heavy the impact of this limitation of not having "just my code" option should be.

Any ideas of any other causes?
