ClassCastException when using services as dynamic proxies
---------------------------------------------------------
Key: FELIX-552
URL: https://issues.apache.org/jira/browse/FELIX-552
Project: Felix
Issue Type: Improvement
Components: iPOJO
Environment: Sun HotSpot JVM 1.6.0u4 + JOnAS 5.0.1
Reporter: Kiev Gama
Priority: Minor
In a changed OSGi implementation that uses dynamic proxies for services, iPOJO
presents a typecast error.
iPOJO's implementation seems to rely on a service instance of
org.apache.felix.ipojo.HandlerFactory, but actually in this particular OSGi
customization that service is dynamically replaced by a proxied service which
implements org.apache.felix.ipojo.Factory.
