             Summary: PortUnreachable not check while writing to socket
                 Key: DIRMINA-1137
                 URL: https://issues.apache.org/jira/browse/DIRMINA-1137
             Project: MINA
          Issue Type: Bug
          Components: Core
    Affects Versions: 2.1.4
         Environment: Java 1.8, Unix/Windows
            Reporter: Alexander B


Hi guys,

My intention is to send udp package to a specific ip and port (even if there is not receiver).
Me - as the sender - do not have any knowledge about (existing) receivers. After receiving
a "unreachable port" package back to myself (because no receiver exists), the session was
closed automatically.

In your class AbstractPollingIoProcessor from lines 1108ff. in such a case a UnreachablePortException
was thrown, catched and therefore in line 1112 the session was closed.

In contrast to this, while reading from a socket (lines 560ff.), you are distinguishing cases
with and without the flag CloseOnPortUnreachable from the sessionConfig. [I am not quite sure
about my statement here]

Can you explain, why this was not done at the "writing"-process? Or was there anything I missunderstood?

Thanks
Alex
