--------------------------------------

             Summary: Concurrent access during startup
                 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: C=C3=A9dric Casenove


We use the configuration admin to create iPojo instances at runtime. During=
 Felix startup, an error may happen because 2 threads (one from iPOJO Insta=
nce Creator, the other from Configuration Admin) are accessing a list at th=
e same time:
