ClassCastException on element update

[Srdjan-V]

If a repository gets open by clearing it, the type of the db will stay Object causing class cast exceptions while deserializing.

    @Data
    @Entity
    @AllArgsConstructor
    @NoArgsConstructor
    public static class TestEntity {
        @Id
        String name;
        String data;
    }

    void execute() {
        File file = new File(FileUtils.getTempDirectory(), "db_test");
        file.deleteOnExit();

        RocksDBModule storeModule = RocksDBModule.withConfig()
                .filePath(file)
                .build();

                    return super.convertFromDocument(source, type);
                } catch (IllegalArgumentException | ObjectMappingException e) {

        };
        for (Module jacksonModule : List.of(

            jacksonMapper.registerJacksonModule(jacksonModule);
        }

        Nitrite nitrite = Nitrite.builder()
                .loadModule(storeModule)
                .loadModule(NitriteModule.module(jacksonMapper))
                .openOrCreate();


        ObjectRepository<TestEntity> repository = nitrite.getRepository(TestEntity.class, "K");

        // this will open a NitriteMap<Object, Object>
        repository.clear();

        repository.update(new TestEntity("SS", "S"), true);

    }
