To reproduce exception you need to:
1) Stop(not shutdown) some SA with ant-tasks or jconsole;
2) Stop/kill ServiceMix;
3) Start ServiceMix;
4) Send some message through static-routing-slip endpoint;
Based on source code analyze -- problem in 'store' initialization and affects
all servicemix-eip endpoints, but not in SA/SU state restoration. It seems
SA/SU state restoration procedure conforms to JBI spec.
There is general question how eip endpoints should work in 'stopped' state from
JBI point of view? Perhaps eip endpoints should send Fault messages in
'stopped' state.
