Reports class references that will resolve to a different class at runtime than at compile time.

Example:

  MainModule
  ├── DepModule
  │   └── Av1.jar  ← my.example.A (will be used at runtime!)
  └── Av2.jar      ← my.example.A (used at compile time)

The IDE resolves A from Av2, but the JVM loads it from Av1. Calling a method that exists only in Av2 causes NoSuchMethodError.

Fix: move Av2 before DepModule so both compile and runtime use the same class.
