Unable to run Modulith with AOT

[mrudolph1986]

I am trying to use modulith with AOT for graalvm and it fails to initiate the MomentProperties:

Exception in thread "main" java.lang.IllegalStateException: No constructor or factory method candidate found for Root bean: class [org.springframework.modulith.moments.support.MomentsProperties]; scope=singleton; abstract=false; lazyInit=null; autowireMode=0; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=null; factoryMethodName=null; initMethodNames=null; destroyMethodNames=null and argument types [] at org.springframework.beans.factory.support.ConstructorResolver.resolveConstructorOrFactoryMethod(ConstructorResolver.java:947) at org.springframework.beans.factory.support.RegisteredBean.resolveConstructorOrFactoryMethod(RegisteredBean.java:212) at org.springframework.beans.factory.aot.BeanDefinitionMethodGenerator.<init>(BeanDefinitionMethodGenerator.java:86) at org.springframework.beans.factory.aot.BeanDefinitionMethodGeneratorFactory.getBeanDefinitionMethodGenerator(BeanDefinitionMethodGeneratorFactory.java:100) at org.springframework.beans.factory.aot.BeanDefinitionMethodGeneratorFactory.getBeanDefinitionMethodGenerator(BeanDefinitionMethodGeneratorFactory.java:115) at org.springframework.beans.factory.aot.BeanRegistrationsAotProcessor.processAheadOfTime(BeanRegistrationsAotProcessor.java:49) at org.springframework.beans.factory.aot.BeanRegistrationsAotProcessor.processAheadOfTime(BeanRegistrationsAotProcessor.java:37) at org.springframework.context.aot.BeanFactoryInitializationAotContributions.getContributions(BeanFactoryInitializationAotContributions.java:67) at org.springframework.context.aot.BeanFactoryInitializationAotContributions.<init>(BeanFactoryInitializationAotContributions.java:49) at org.springframework.context.aot.BeanFactoryInitializationAotContributions.<init>(BeanFactoryInitializationAotContributions.java:44) at org.springframework.context.aot.ApplicationContextAotGenerator.lambda$processAheadOfTime$0(ApplicationContextAotGenerator.java:58) at org.springframework.context.aot.ApplicationContextAotGenerator.withCglibClassHandler(ApplicationContextAotGenerator.java:67) at org.springframework.context.aot.ApplicationContextAotGenerator.processAheadOfTime(ApplicationContextAotGenerator.java:53) at org.springframework.context.aot.ContextAotProcessor.performAotProcessing(ContextAotProcessor.java:106) at org.springframework.context.aot.ContextAotProcessor.doProcess(ContextAotProcessor.java:84) at org.springframework.context.aot.ContextAotProcessor.doProcess(ContextAotProcessor.java:49) at org.springframework.context.aot.AbstractAotProcessor.process(AbstractAotProcessor.java:82) at org.springframework.boot.SpringApplicationAotProcessor.main(SpringApplicationAotProcessor.java:80)

If I configure "spring.modulith.moments.enabled: false" it seems to be working, but now I am missing some features.

I've fixed this by introducing a private default constructor for now. Upstream ticket filed for Spring Framework as it should be able to handle the class without one, too, as it does in the non AOT case.
