- `FirJavaFacade.knownClassNamesInPackage` cannot be computed in the IDE using the current strategy because there are multiple finders and there is no `CliFinder`. However, the cache was still used, which caused it to be filled with `null` values and additionally caused worse performance in `JavaSymbolProvider` due to hash map accesses via `hasTopLevelClassOf`. - Rewriting the strategy is non-trivial as additional indices are needed on the IDE side.
