Roberto Cortez commented on TOMEE-2458:
---------------------------------------
[~dkwakkel] I believe [~romain.manni-bucau] is right.
The problem here is that some of the MP libs require Bean injection on their
Extensions. So, the Extension is loading, but their CDI beans are not, hence
you get that weird NPE.
Most likely, the CDI Extensions are being loaded by one class loader and their
beans scanning by another loader, or not even scanned at all.
Can you have a look here
org.apache.openejb.config.DeploymentLoader#addBeansXmls(org.apache.openejb.config.WebModule).
This is where the url list of jars is obtained to perform CDI scanning for
beans. So, it needs to return all the MP libs in here.
