------------------------------------
Summary: Fix for ARIES-1216 can cause NPE if classToProxy is a
class from the boot loader
Key: ARIES-1238
URL: https://issues.apache.org/jira/browse/ARIES-1238
Project: Aries
Issue Type: Bug
Components: Proxy
Reporter: Thomas Watson
I'm not entirely sure on the scenario to reproduce this. But I was getting an
NPE when the classToProxy is a class from the boot strap class loader. In my
scenario I think that class is java.util.Properties:
