Document AOT limitations related to Kotlin identifiers with backticks #32487
Description
Affects: <6.1.2>
Reproducer: https://github.com/juliuskrah/graphql-demo/tree/spf-32487
Given this valid kotlin class:
class `20240318CreateProductTable` { fun createProductTable() { } fun addProductData() { } }and Bean class:
class ExampleBean { lateinit var migrationClass: Class<*> }with a runtime bean definition:
@Configuration(proxyBeanMethods = false) class MyConfig { companion object { @Bean fun beanProcessor(): BeanFactoryPostProcessor { return BeanFactoryPostProcessor { if (it is DefaultListableBeanFactory) { val beanDefinition = BeanDefinitionBuilder.rootBeanDefinition(ExampleBean::class.java) .addPropertyValue("migrationClass", com.example.graph.migration.`20240318CreateProductTable`::class.java) .beanDefinition it.registerBeanDefinition("exampleBean", beanDefinition) } } } } }generates the following invalid java class:
import com.example.graph.migration.20240318CreateProductTable; import org.springframework.aot.generate.Generated; import org.springframework.beans.factory.config.BeanDefinition; import org.springframework.beans.factory.support.RootBeanDefinition; @Generated public class ExampleBean__BeanDefinitions { /** * Get the bean definition for 'exampleBean'. */ public static BeanDefinition getExampleBeanBeanDefinition() { RootBeanDefinition beanDefinition = new RootBeanDefinition(ExampleBean.class); beanDefinition.getPropertyValues().addPropertyValue("migrationClass", 20240318CreateProductTable.class); beanDefinition.setInstanceSupplier(ExampleBean::new); return beanDefinition; } }that results in:

Expectation
Kotlin sources should generate Kotlin aotSources
