NPE when modifying properties of lazy (uninstantiated) service
--------------------------------------------------------------
Key: FELIX-2213
URL: https://issues.apache.org/jira/browse/FELIX-2213
Project: Felix
Issue Type: Bug
Components: Declarative Services (SCR)
Affects Versions: scr-1.4.0
Environment: Win XP
Reporter: Alex Mulholland
Fix For: scr-1.4.0
Service A is active and has a reference (ServiceReference) to Service B.
Service B is not immediate and has not been activated. If at this point I
update the properties for Service B in ConfigAdmin, I get the NPE below. The
code appears to be going down the 'modified' path but I don't think that is
appropriate in this scenario; I expected the new properties to be 'cached' by
SCR until the service was activated. Workaround: if I resolve the
ServiceReference to service B (causing it to activate) BEFORE updating the
properties in ConfigAdmin, the problem does not occur and the modified method
for service B is driven correctly.
