Subject [jira] Created: (FELIX-539) Intermittent IllegalArgumentException while using declarative services

Intermittent IllegalArgumentException while using declarative services   
-------------------------------------------------------------------------

                 Key: FELIX-539
                 URL: https://issues.apache.org/jira/browse/FELIX-539
             Project: Felix
          Issue Type: Bug
          Components: Declarative Services (SCR)
    Affects Versions: felix-1.0.4
            Reporter: Rajini Sivaram


I get an intermittent (very rare) exception while running tests using declarative services
under Felix. 
 
The exception stack trace shows:
 
java.lang.IllegalArgumentException: Service object cannot be null.
        at org.apache.felix.framework.Felix.registerService(Felix.java:2661)
        at org.apache.felix.framework.BundleContextImpl.registerService(BundleContextImpl.java:254)
        at org.apache.felix.scr.impl.AbstractComponentManager.registerComponentService(AbstractComponentManager.java:598)
        at org.apache.felix.scr.impl.AbstractComponentManager.activateInternal(AbstractComponentManager.java:426)
        at org.apache.felix.scr.impl.AbstractComponentManager.enableInternal(AbstractComponentManager.java:323)
        at org.apache.felix.scr.impl.AbstractComponentManager.access$000(AbstractComponentManager.java:36)
        at org.apache.felix.scr.impl.AbstractComponentManager$1.run(AbstractComponentManager.java:94)
        at org.apache.felix.scr.impl.ComponentActorThread.run(ComponentActorThread.java:85)
 
Whenever I have seen the exception, logs suggest that the components were being reactivated
at around the same time. The stack trace from the debugger when reactivate occurs shows:
 
        ImmediateComponentManager.disposeImplementationObject(Object, ComponentContext) line:
273
        ImmediateComponentManager.deleteComponent() line: 151
        ImmediateComponentManager(AbstractComponentManager).deactivateInternal() line: 469
        ImmediateComponentManager(AbstractComponentManager).reactivate() line: 142
        ImmediateComponentManager.reconfigure(Dictionary) line: 399
        ImmediateComponentManager$1.updated(Dictionary) line: 90
        ConfigurationManager$ManagedServiceUpdate.run() line: 863
        UpdateThread.run() line: 89
 
Would it be possible to introduce some synchronization during activate/deactivate to avoid
the service/component being set to null? I am using Felix framework 1.1.0-SNAPSHOT and SCR
1.0.0.
