我们有一个常规的CDI bean，我们在其中声明一个方法：
@Named
@ViewScoped
@LoggedIn
public class ComplianceRuleDocumentationManager extends BaseStatusShownDataManager<CcDocumentation>
{
...
@Override
protected Class<?> getTargetClass()
{
// TODO Auto-generated method stub
return null;
}
}
项目没有编译错误。
部署到GlassFish 3.2.x后，登录并重定向到主页面（仪表板）会导致以下异常（ComplianceRuleDocumentationManager只是该页面可以访问的许多应用程序之一）：

我可以看到JRebel尝试重新加载类ComplianceRuleDocumentationManager，但我不知道它为什么会这样做，因为我在完全重新启动服务器之前清理了GlassFish部署目录和其他一些东西（我们有一个相当稳定的清理脚本）。
任何可能导致此问题的想法？为什么getTargetClass()方法会影响/导致此问题？
由于
