Describe the bug

The above breakpoints are ignored when pressing "debug". The program just executes until it is finished without stopping at any breakpoints.

Metals version tested:

sbt 1.8.2

Windows 11

Expected behavior

Breakpoints should be respected

Operating system

Windows

Editor/Extension

VS Code

Version of Metals

0.11.10

case class Person(a: Int, b: String)
case class Banana(a: Int, b: String)

trait CanEat[A, B]:
  def eat(eater: A, eatMe: B): Unit

extension[X] (x: X)
  def eat[Y](y: Y)(using CanEat[X, Y]): Unit =
    println("Yo")
    summon[CanEat[X, Y]].eat(x, y)

given CanEat[Person, Banana] with
  def eat(eater: Person, eatMe: Banana): Unit = println(s"$eater eating $eatMe")

@main def hello(): Unit =
  println("start sleeping")
  Thread.sleep(1000)
  println("done sleeping")
  Person(2, "3").eat(Banana(3, "2")) //

I tried reproducing on windows and it seems to work. What Java are you using? Do you see anything in .metals/metals.log ? Could you maybe create .metals/dap-server.trace.json and .metals/dap-client.trace.json? If you run the program again it should save all the json rpc traces there, which we could use to debug. More info about that is here https://scalameta.org/metals/docs/contributors/getting-started#json-rpc-trace

I get this in the metals output/log

After discussion with @tgodzik we got the debugger semi working by adding my main class to a package (instead of the default package)

However, it should be noted that some lines/some breakpoints are ignored at the beginning of the application it seems, presumably if the execution passes them before the debugger has time to connect
