Marcel Schlegel created FELIX-3653:
--------------------------------------
Summary: Define the "@Reference" annotation on class level without
a "referenceInterface" parameter.
Key: FELIX-3653
URL: https://issues.apache.org/jira/browse/FELIX-3653
Project: Felix
Issue Type: Bug
Components: Maven SCR Plugin
Affects Versions: maven-scr-plugin-1.8.0
Reporter: Marcel Schlegel
Priority: Minor
If there is no "referenceInterface" parameter defined by the "@Reference"
annotation on class level, the maven-scr-plugin throws a hard
"NullPointerException" instead of a normal error log "SCR Descriptor parsing
had failures".
StackTrace:

failed. NullPointerException -> [Help 1]
