[jira] Created: (AXIS2-4504) ConcurrentModificationException when
running axis2 as OSGi bundle with a configadmin
ConcurrentModificationException when running axis2 as OSGi bundle with a configadmin
------------------------------------------------------------------------------------
Key: AXIS2-4504
URL: https://issues.apache.org/jira/browse/AXIS2-4504
Project: Axis 2.0 (Axis2)
Issue Type: Bug
Affects Versions: 1.5
Environment: Equinox 3.5.0 and either the Equinox or the Felix Configuration Admin Service
Reporter: Kristoffer Peterhänsel
Running the axis2 OSGi bundle in an environment with a Configuration Admin Service installed seems to provoke an ConcurrentModificationException. Specifically if the Configuration Admin Service is started before the axis2 bundle.
This is the exception I am getting:

------------------------------------------
Attachment: patch.txt
It seems that the problem is BundleTracker#addRegistry is not using the lock. So the lists might be changed by it while another thread is running though it. At least adding the lock seems to have fixed this issue.
So I submit this simple patch.
