Http proxy doesnt reconnect upon lost fix session

Fix engine (initiator) doesnt reconnect upon the acceptor's restart when http proxy is being used. It keeps displaying "Pending connection not established after 270734 ms.", which is a consequence of not reconnecting at all. Is there any workaround for http proxy to trigger reconnection?

We have configured ReconnectInterval, ProxyType=http, ProxyVersion=1.1.

If we change proxy type to socks we are seeing the reconnect attempt due to /org/apache/mina/proxy/ProxyConnector.java:181, but would be nice to have the same functionality for http proxy. I also cant see any obvious way to set reconnectionNeeded variable that would potentially trigger the reconnection which i have tested by resetting it myself with a debugger.
