Add injection point information to exception message when injection into
observer fails
---------------------------------------------------------------------------------------
Key: WELD-870
URL: https://issues.jboss.org/browse/WELD-870
Project: Weld
Issue Type: Enhancement
Components: Events
Affects Versions: 1.1.0.Final
Reporter: Dan Allen
Injections that fail when an observer method is invoked are massively hard to
track down. Here's the information you get:
org.jboss.weld.exceptions.IllegalArgumentException: WELD-001324 Argument bean
must not be null

I expect to see the type and qualifiers at the failing injection point.
