When a bean doesn't pass the verifier it is "undeployed" and in our case the LRU cache barf an NPE. It doesn't look very good and probably has to do with some "non-initialized" field that is supposed to do some work. We can predictably say that people will screw their deployment and the error they get is container NPE which is confusing. Can someone take a look at it? No don't point the fingers back at me, I am running on the training. <snip the bean fails> (this happens for all failed beans) [J2EE Deployer Default] Starting BookStockBean.jar failed!
