> Key: FELIX-3548
> URL: https://issues.apache.org/jira/browse/FELIX-3548
> Project: Felix
> Issue Type: Bug
> Components: iPOJO
> Affects Versions: ipojo-core-1.8.2
> Environment: Felix distribution 4.0.2, iPojo 1.8.2, Oracle JVM
> 1.6.0_29, Windows XP 32
> Reporter: Cédric Casenove
> Assignee: Clement Escoffier
> Fix For: ipojo-core-1.8.4
>
>
> We use the configuration admin to create iPojo instances at runtime. During
> Felix startup, an error may happen because 2 threads (one from iPOJO Instance
> Creator, the other from Configuration Admin) are accessing a list at the same
> time:
