When you get stack traces with this in it:
当您在其中获得堆栈跟踪时：
java.lang.NullPointerException
at org.jboss.mx.loading.RepositoryClassLoader.findClass(RepositoryClassLoader.java:623)
It usually means that JBoss's classloader has got itself into an unrecoverable state, and the loading of certain core classes fails, which occasionally happens after a lot of hot deployments.
这通常意味着JBoss的类加载器进入了不可恢复的状态，某些核心类的加载失败，这种情况偶尔会在大量热部署后发生。
In my experience, it is usually fixed by a JBoss restart.
根据我的经验，它通常通过 JBoss 重启来修复。
回答by Hopkroft
Check the list:
1. You must have dafault constructor with no-arg
2. Constructor must be public
检查列表：
1. 您必须具有无参数的 dafault 构造函数
2. 构造函数必须是公共的
回答by Blaisorblade
The stack trace is quite complex, you'd better ask to JBoss developers on the JBoss mailing lists/forums, or open a bug report (given that there is a java.lang.NullPointerException, it is surely a bug).
堆栈跟踪相当复杂，您最好在 JBoss 邮件列表/论坛上询问 JBoss 开发人员，或者打开一个错误报告（假设有一个 java.lang.NullPointerException，它肯定是一个错误）。
Anyway, given that the error is reported in:
无论如何，鉴于错误报告在：
org.jboss.mx.loading.RepositoryClassLoader.findClass(RepositoryClassLoader.java:623)
it's a problem during class loading, while looking for some class. You can either look at sources of org.jboss.mx.loading.RepositoryClassLoader (line 623) to see if you find anything useful, or directly ask for support elsewhere.
这是在类加载过程中的一个问题，同时寻找一些类。您可以查看 org.jboss.mx.loading.RepositoryClassLoader 的源代码（第 623 行）以查看是否有任何有用的东西，或者直接在其他地方寻求支持。
回答by THIHA SOE
You should be use this property in hibernate.cfg.xml
您应该在 hibernate.cfg.xml 中使用此属性
<property name="hibernate.bytecode.use_reflection_optimizer">false</property>
if there is no reason using javaassit.jar, should remove that jar file from project build path, that all can solve it easily since i have solved this way.
如果没有理由使用 javaassit.jar，应该从项目构建路径中删除那个 jar 文件，因为我已经解决了这个问题，所以所有的都可以轻松解决。
