> After deploying daytrader, if you apply heavy load (50 threads) you get about 60 exceptions like this:

> Looking into the code, it appears that cglib is calling EJBMethodInterceptor with a null methodProxy. After these startup exceptions, which appear to occur within the first 2 seconds of load, there are no further exceptions: i ran it for 17 minutes at 1200 pages/sec.
