use of org.springframework.data.convert.ReflectionEntityInstantiatorUnitTests.Outer.Inner in project spring-data-commons by spring-projects.

the class ReflectionEntityInstantiatorUnitTests method createsInnerClassInstanceCorrectly.

// DATACMNS-134
@Test

        Inner instance = INSTANCE.createInstance(entity, provider);
        assertThat(instance).isNotNull();
        // Hack to check synthetic field as compiles create different field names (e.g. this$0, this$1)
        ReflectionUtils.doWithFields(Inner.class, field -> {
            if (field.isSynthetic() && field.getName().startsWith("this$")) {
