[jira] [Created] (FELIX-4488) Attempt to create nullable object for
non-interface service
Clement Escoffier created FELIX-4488:
----------------------------------------
Summary: Attempt to create nullable object for non-interface service
Key: FELIX-4488
URL: https://issues.apache.org/jira/browse/FELIX-4488
Project: Felix
Issue Type: Bug
Components: iPOJO
Affects Versions: ipojo-runtime-1.11.2
Reporter: Clement Escoffier
Fix For: ipojo-runtime-1.11.3
iPOJO tries to create nullable object for non-interface services. It should return 'null' in this case.
Here is the stack trace:
