我在J2EE容器中偶尔会收到以下错误。这是容器起床的一段时间，没有任何问题，有时候容器没有出现，因为这个错误，有没有人看到过这个错误......？可能是什么原因..？它涉及任何类加载器/安全问题..？

答案 0 :(得分：2)
AUTHav.class已损坏（有时？）。显然，某些方法被声明为抛出不是Throwable的子类的东西。通常这不应该发生，因为Java编译器会检测到该问题并报告错误。但也许类文件被修改/检测，甚至在运行时生成，这引入了偶发错误。或者你有一个命名冲突，并且classloaded偶尔会看到一个不同的非Throwable类而不是预期的类。
如果某个档案中包含AUTHav.class，您可以查看字节代码（使用javap或反编译器）并检查是否找到了可疑throws的方法参数。
所以字节代码被混淆了......那么它可能是 - 这只是猜测 - 你的J2EE容器中有多个版本的库。由于类是混淆的，因此类名AUTHa7和/或AUTHa1有可能用于不同版本库中的不同（原始）类。然后，如果类加载器在错误的时间拾取了两个或者错误的一个，那么可能会发生AUTHa7和/或AUTHa1在运行时不是例外...

我的猜测：错误的硬件，特别是RAM，导致JVM损坏字节码。通常它会导致彻底的JVM崩溃，但它肯定值得一试：
