实体类的getHibernateLazyInitializer中的NullPointerException

Question

我遇到以下异常：

在中等/高负载下启动应用程序后，这往往会很快发生。类的进一步实例化com.Customer由于相同的异常而失败，因此该应用程序实际上被破坏了，直到我们重新启动为止。

我已经遍历了代码，但是由于将其设置在中，因此无法看到将如何DefaultMethodHandler调用theCustomer_$$_javassist_1它们JavassistLazyInitializer。

这是在带有Javassist 3.16.1的Hibernate 3.6.8-Final上

谁看过这个吗？有没有可能的解决方法？
