Spring Integration Обработка исключений SFTP

Я конвертирую каждое входящее сообщение в файл и загружаю на SFTP-сервер. Я получаю огромные журналы трассировки стека исключений, когда SFTP недоступен во время загрузки файла. Это происходит при каждом входящем сообщении. Просто интересно, есть ли какое-нибудь более чистое решение, где я могу перехватывать эти исключения и регистрировать настраиваемое сообщение с помощью моего КОНФИГУРИРОВАННОГО РЕГИСТРАТОРА?

   <bean id="sftpSessionFactory" class="org.springframework.integration.sftp.session.DefaultSftpSessionFactory">
        <property name="host" value="${ftp.host}"></property>
        <property name="port" value="22" />
        <property name="user" value="${ftp.username}"></property>
        <property name="password" value="${ftp.password}"></property>
        <property name="timeout" value="2000"></property>
    </bean>

    <int:publish-subscribe-channel id="sftpChannel"></int:publish-subscribe-channel>
    <sftp:outbound-channel-adapter id="sftpOutboundAdapter" auto-create-directory="true" session-factory="sftpSessionFactory" channel="sftpChannel" charset="UTF-8" remote-directory="${ftp.path}" remote-filename-generator-expression="headers[fileName] + '.xml'">
        <sftp:request-handler-advice-chain>
            <bean class="org.springframework.integration.handler.advice.ExpressionEvaluatingRequestHandlerAdvice">
                <property name="onSuccessExpression" value="payload.delete()" />
            </bean>
        </sftp:request-handler-advice-chain>
    </sftp:outbound-channel-adapter>

Я изменил конфигурацию, как показано ниже:

<int:publish-subscribe-channel id="sftpChannel"></int:publish-subscribe-channel>
<sftp:outbound-channel-adapter id="sftpOutboundAdapter" auto-create-directory="true" session-factory="sftpSessionFactory" channel="sftpChannel" charset="UTF-8" remote-directory="${spectrum.ftp.path}" remote-filename-generator-expression="headers[fileName] + '.xml'">
    <sftp:request-handler-advice-chain>
        <bean class="org.springframework.integration.handler.advice.ExpressionEvaluatingRequestHandlerAdvice">
            <property name="onSuccessExpression" value="payload.delete()" />
            <property name="failureChannel" ref="errorChannel" />
        </bean>
    </sftp:request-handler-advice-chain>
</sftp:outbound-channel-adapter>

Я отправляю этот файл, используя:

    outputChannel = context.getBean("sftpChannel", org.springframework.integration.MessageChannel.class);
line#120->     if (outputChannel.send(payload)) {
                        ptsoLog.info("Successfully uploaded file : " + fileName + ".xml");
                    }else{
                        ptsoLog.error("File upload failed : " + e.getMessage());
                    }

но все равно получите это исключение:
