Subject [jira] [Created] (DIRMINA-1033) Expose METADATA parameter for NioDatagramSession

Tunca Tunc created DIRMINA-1033:
-----------------------------------

             Summary: Expose METADATA parameter for NioDatagramSession
                 Key: DIRMINA-1033
                 URL: https://issues.apache.org/jira/browse/DIRMINA-1033
             Project: MINA
          Issue Type: Bug
          Components: Transport
    Affects Versions: 2.0.13
         Environment: Centos 7, Windows 7
            Reporter: Tunca Tunc
            Priority: Minor
             Fix For: 2.0.14


The CumulativeProtocolHandler doesn't accumulate for UDP transport.
It's because METADATA for NioDatagramSession is creates as

static final TransportMetadata METADATA = new DefaultTransportMetadata("nio", "datagram",
true, false, InetSocketAddress.class, DatagramSessionConfig.class, IoBuffer.class);

Where 4th parameter is fragmentation parameter. Thus it thinks there are no fragmentation
for UDP transport.

NioDatagramSession METADATA should be created as:
    static final TransportMetadata METADATA = new DefaultTransportMetadata("nio", "datagram",
true, true,
            InetSocketAddress.class, DatagramSessionConfig.class, IoBuffer.class);

Where 4th parameter is true, marking fragmentation is true for UDP.

Or the METADATA parameter can be exposed to developer.
