Preserve cast on generic method invocation in overloaded outer call#891
Merged
Conversation
When a cast wraps a generic method invocation whose declared return is a type variable (e.g. `(Object) cursor.getValue()` where `<T> T getValue()`), the cast pins the inferred return type so an overloaded outer call like `StringBuilder.append` resolves unambiguously. The LST resolves the invocation's return to its bound (Object), so the existing `castType.equals(expressionType)` shortcut dropped the cast before the `hasMethodOverloading` check could run. Detect the generic return on the declaring class and preserve the cast when the parent call is overloaded.
Dedupe the declaring-type method-loop between the new MethodCall branch and the existing Lambda-body branch. Also hoist the cheap `hasMethodOverloading` check above the loop so non-overloaded parent calls short-circuit without scanning the declaring type's methods.
