Katya Todorova commented on TOMEE-2055:
---------------------------------------
Romain, thank you for looking into this. My test app still throws NPE, it's in
fact the code that is creating the "produce" object which is causing it:
{code} final T produce =
super.produce(super.createInterceptorInstances(ccImpl), ccImpl); {code}
And as far as I can see from you fix, the null check is done after the produce
invocation. Checking the result for null may fix another scenario, but in my
case the new code that is responsible for creating the interceptor instances is
not invoked.
When super.produce is invoked, should the interceptor instances be already
created in all cases?
