最近发现部署在weblogic上面的应用restart的时候报NullPointException错误，由于系统ejb构建比较复杂，在stateless ejb之上还有个stateless ejb来实现cache的功能，一直以为是多层bean导致weblogic restart ear出错，左调整右调整都不行，网上google也没有进展，最后跑去oracle support网站，一search，才发现有人报了类似的问题，oracle为weblogic10.3.3出了patch。。。好伤感，折腾了这么久，不能太相信第三方的软件......

“The stateless session EJB home associated to the bean with the remote interface oracle.j2ee.tests.ejb.impl.DoclitWrapperWTJPortType, is not being unexported from OIDManager during the stop (deactivate) phase of the application lifecycle. This is causing the previous uninitialized object to be returned. The NullPointerException seen is a result of creating the message associated to the AssertionError that was going to be thrown since the object is in an uninitialized state. This issue is addressed by unpublished defect 9504078.”
