>          Issue Type: Bug
>            Reporter: Matt Pavlovich
>            Assignee: Matt Pavlovich

> Need a class instance level lock or duplicate list around the broker map when 
> doing a .destroy() caused by bundle refesh
> Calling .destroy() loops over a map which calls deleted.. which fails when 
> there is more than one bundle and the bundle is shutdown first (not a 
> service(s) removed via .cfg delete or osgi service shutdown lifecycle).
> #1. OSGi calls.. 
> {noformat}
>     synchronized public void destroy() {
>         for (String broker : brokers.keySet()) {
>             deleted(broker);
>         }
>     }
> {noformat}
> #2. Which blows up here.. due to concurrent modification on the _brokers_ 
> collection
> {noformat}
>     @Override
>     synchronized public void deleted(String pid) {
>         ServiceRegistration<BrokerService> reg = brokerRegs.remove(pid);
>         if (reg != null) {
>             reg.unregister();
>         }
>         BrokerService broker = brokers.remove(pid);
>         if (broker != null) {
>             stop(pid, broker);
>         }
