Description

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?
