> Key: FELIX-1846
> URL: https://issues.apache.org/jira/browse/FELIX-1846
> Project: Felix
> Issue Type: Bug
> Components: Declarative Services (SCR)
> Affects Versions: scr-1.2.0
> Environment: Java 1.5 on Mac, Felix 2.0.1 started by Pax Runner,
> build based on Revision: 832970 from
> http://svn.apache.org/repos/asf/felix/trunk
> Reporter: Zachery Jensen
> Assignee: Felix Meschberger
> Priority: Blocker
> Fix For: scr-1.4.0
>
>
> If the target filter is undefined for a component before a change is made to
> its configuration (in this case, by way of config admin and fileinstall) it
> will always throw this NullPointerException because the clause at the
> associated line of code is bad. It doesn't sufficiently guard for null
> return values for getTarget() before potentially dereferencing off
> getTarget()'s return.
> Workaround is to set any target filter, though that's not an acceptable
> workaround in my opinion... at least it works.
> If a target filter is set it seems to work as expected.
> *ERROR* Unexpected problem delivery configuration event to
