Thanks, Felix.

> Key: FELIX-2289
> URL: https://issues.apache.org/jira/browse/FELIX-2289
> Project: Felix
> Issue Type: Bug
> Components: Declarative Services (SCR)
> Affects Versions: scr-1.4.0
> Reporter: Felix Meschberger
> Assignee: Felix Meschberger
> Priority: Critical
> Fix For: scr-1.4.2
>
>
> The ComponentFactoryImpl class manages all factory component instance in an
> internal IdentityHashMap. This map is synchronized thus all access in a
> multi-thread environment must be synchronized.
> Most access is synchronized. The problematic one not synchronized is when a
> new entry is added. Making this call unsynchronized causes the map to get
> corrupt and will lead to endless loops when reading it.
