[jira] [Resolved] (ARIES-1498) NullPointerException NPE Blueprint
Container AbstractServiceReferenceRecipe setSatisfied
[ https://issues.apache.org/jira/browse/ARIES-1498?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Guillaume Nodet resolved ARIES-1498.
------------------------------------
Resolution: Fixed
Assignee: Guillaume Nodet
Fix Version/s: blueprint-core-1.6.0
I think the setSatisfied might be called after stop() because I'm not sure about the concurrency in the OSGi framework for the ServiceListener being called and its removal.
I've added the volatile keyword and also an additional check.
