-----------------------------------------------------------------
I've just tested the method suggested by Paul. With a single session cache in
the instance of IoSessionRecycler I hit the same issue: only a first (wrong)
session is matched due to misuse of receiver socket information.
However if I subclass IoSessionRecycler and apply two different instances to
two acceptors, it works good:
{{acceptor_auth = new NioDatagramAcceptor();}}
acceptor_auth.setHandler(new RadiusServerHandler());
acceptor_auth.setSessionRecycler(new MyIoSessionRecycler());
{{acceptor_acct = new NioDatagramAcceptor();}}
acceptor_acct.setHandler(new RadiusServerHandler());
acceptor_acct.setSessionRecycler(new MyIoSessionRecycler());
{{try {}}
{{ acceptor_auth.bind(new InetSocketAddress(1812));}}
{{ acceptor_acct.bind(new InetSocketAddress(1813));}}
} catch (IOException e) {}}
{{ e.printStackTrace();}}
}
{{...}}

> IoSessionRecycler RemoteAddress Collision
> -----------------------------------------
>
> Key: DIRMINA-996
> URL: https://issues.apache.org/jira/browse/DIRMINA-996
> Project: MINA
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.0.7
> Reporter: Flavio Battimo
> Assignee: Jonathan Valliere
> Priority: Critical
> Fix For: 2.1.4
>
>
> When using NioDatagramAcceptor with multiple binded local addresses the
> IoSessionRecycler is not working as expected.
> If the acceptor has been prefilled with two sessions:
> remoteaddr=192.168.1.10:2001 localaddr=192.168.1.20:1000
> remoteaddr=192.168.1.10:2001 localaddr=192.168.1.20:1001
> so with same remote address but different local address, when the recycle
> method of IoSessionRecycler interface is called only remote address is
> passed. The recycler returns the same IoSession for incoming datagrams on two
> different local addresses of the same acceptor.
> The IoSessionRecycler should have the local address parameter also in order
> to find the correct IoSession.
