[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.
This is link to the mailing list discussion.
