Cédric Casenove created FELIX-3548:
--------------------------------------
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: Cédric 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 Instance
Creator, the other from Configuration Admin) are accessing a list at the same
time:
