CODI + WELD:专门化bean必须扩展另一个bean

Question

我有一个EE应用程序，它使用JSF 2.0 (impl 2.1.6)。我使用的服务器是glassfish 3.1.2，CDI实现是WELD。有时，当我运行应用程序时，我会得到以下异常：

org.jboss.weld.exceptions.DefinitionException: WELD-000047 Specializing bean must extend another bean:  Managed Bean [class org.apache.myfaces.extensions.cdi.jsf2.impl.Jsf2ModuleStartupObserver] with qualifiers [@Any @Default]

它并不总是发生；当它发生时，如果我再次运行应用程序，它就可以正常工作。但这很烦人，我想知道为什么会发生这种情况。有人知道吗？

Answer 1

我可以通过遵循http://os890.blogspot.co.at/2012/05/slides-myfaces-codi-and-seam3-become.html中的常见陷阱提示(幻灯片#32+)来解决我使用Glassfish3的所有问题

Answer 2

听起来像是Glassfish CDI集成中的一个bug。我建议给他们的JIRA加一张票。
