          Issue Type: Bug
            Reporter: J.W. Janssen
            Assignee: J.W. Janssen


Sometimes, I see the following exception occur in my logs:

java.util.ConcurrentModificationException
	at java.util.HashMap$HashIterator.nextEntry(HashMap.java:793)
	at java.util.HashMap$EntryIterator.next(HashMap.java:834)
	at java.util.HashMap$EntryIterator.next(HashMap.java:832)
	at org.apache.ace.client.repository.impl.RepositorySet.isModified(RepositorySet.java:95)
	at org.apache.ace.client.repository.impl.RepositoryAdminImpl.isModified(RepositoryAdminImpl.java:305)
	at org.apache.ace.webui.vaadin.component.MainActionToolbar.handleEvent(MainActionToolbar.java:269)
	at org.apache.felix.eventadmin.impl.tasks.HandlerTaskImpl.execute(HandlerTaskImpl.java:87)
	at org.apache.felix.eventadmin.impl.tasks.SyncDeliverTasks$1.run(SyncDeliverTasks.java:234)
	at EDU.oswego.cs.dl.util.concurrent.PooledExecutor$Worker.run(Unknown Source)
	at java.lang.Thread.run(Thread.java:680)

It appears that RepositoryAdminImpl is not entirely threadsafe.
