> Multiple threads running through composite activation can cause concurrent modification, like so:
> java.util.ConcurrentModificationException
> 	at java.util.AbstractList$SimpleListIterator.next(AbstractList.java:64)
> 	at org.apache.tuscany.sca.core.assembly.CompositeActivatorImpl.addImplementationProvider(CompositeActivatorImpl.java:490)
> 	at org.apache.tuscany.sca.core.assembly.CompositeActivatorImpl.activate(CompositeActivatorImpl.java:989)
> DefaultProviderFactoryExtensionPoint seems to be causing the problem.
