Moritz Bechler commented on AXIS2-5329:
---------------------------------------
I'm also experiencing this issue (org.eclipse.osgi_3.8.0,
org.apache.axis2.osgi_1.0.0.2/1.6.2). As the backtrace below shows the issue
seems to be caused by an active configuration manager
(org.eclipse.equinox.cm_1.0.300.201207151509) which concurrently with the
BundleActivator calls into OSGiConfigurationContextFactory.updated(). Judging
from the OSGI CM spec this is expected behaviour as update() is called from the
Activator after registering the ManagedService which means it is (or might be)
already managed by the configuration manager.
