带有 Java 接口的 Kotlin EJB 抛出 UndeclaredThrowableException

Question

Java 接口：

public interface IUserSettingManager {

        UserSettingApi updateSetting(Long userId, UserSetting userSettingNew) throws FailUpdateUserSettingException;
    }

Kotlin ejb：

@Stateless

@Local(IUserSettingManager::class)

open class UserSettingManager : DataManager(), IUserSettingManager {

    private companion object {
        private val LOG = LoggerFactory.getLogger(UserSettingManager::class.java)
    }

        @Throws(FailUpdateUserSettingException::class)
        private fun validate(userSetting: UserSetting) {
            if (userSetting.avatar?.length ?: 0 > DBConstant.UUID_VARCHAR_SIZE) {
                throw FailUpdateUserSettingException("avatar length")
            }
        }

        @Throws(FailUpdateUserSettingException::class)
        override fun updateSetting(userId: Long, userSettingNew: UserSetting): UserSettingApi {
            val logger = LOG.silentEnter("updateSetting")

            try {
                validate(userSettingNew)

                .....

            } catch (ex: Exception) {
                val msg = "userId:$userId, user setting:$userSettingNew"

                when (ex) {
                    is FailUpdateUserSettingException -> {
                        logger.debug("$msg, ex:$ex")
                        throw ex
                    }
                    else -> {
                        logger.error(msg, ex)
                        throw FailUpdateUserSettingException(ex.toString())
                    }
                }
            }
        }
    }

带有异常的 Java 类：

公共类 FailUpdateUserSettingException 扩展异常 {

        public FailUpdateUserSettingException() {
this(error);

    }

}

当尝试使用不正确的数据调用 ejb 时，得到异常 UndeclaredThrowableException，结果事务滚动

.....

结果

javax.ejb.EJBTransactionRolledbackException

我没有看到任何远程方法调用或任何序列化，这是此类问题的常见原因，但它可能是类加载器问题吗？ Kotlin 代码实例化的类是从不同的类加载器加载的，而不是 JBoss 检查的类，因此它被视为无法识别的 throwable？

我不确定如何检查。 EJB 容器中的类加载器策略可能 - parent-first vs parent-last？

如果您将 Kotlin 代码替换为始终只是从私有 validate() 方法中抛出该异常的 Java 版本，会发生什么行为，只是为了看看这是否会有所不同？

你用的是什么JDK版本、什么Kotlin版本、什么JBoss版本？
