EMA Java: ChannelDown warning is incorrectly logged at ERROR level in ServerChannelHandler

Guanran

Description

When ServerChannelHandler receives a CHANNEL_DOWN event for a client handle, the event is formatted with Severity.WARNING and guarded by isWarnEnabled(), but it is logged by calling
loggerClient().error().

Relevant source:

https://github.com/Refinitiv/Real-Time-SDK/blob/master/Java/Ema/Core/src/main/java/com/refinitiv/ema/access/ServerChannelHandler.java#L343-L363

if (_serverImpl.loggerClient().isWarnEnabled())

{

    // Build the ChannelDown message...


    _serverImpl.loggerClient().error(

        _serverImpl.formatLogMessage(

            ServerChannelHandler.CLIENT_NAME,

            temp.toString(),

            Severity.WARNING));

}

As a result, the log entry has an ERROR log level even though its internal severity is Warning:

  ERROR [OmmIProviderImpl] loggerMsg

      ClientName: ServerChannelHandler

      Severity: Warning

      Text: Received ChannelDown event on client handle 34

      ...

  loggerMsgEnd

Expected behavior

Since this event is classified as Severity.WARNING and the code checks isWarnEnabled(), it should be logged using warn():

  _serverImpl.loggerClient().warn(

      _serverImpl.formatLogMessage(

          ServerChannelHandler.CLIENT_NAME,

          temp.toString(),

          Severity.WARNING));

Actual behavior

The event is logged using error(), which can trigger false error alerts and make normal client disconnects appear to be application errors.
