I'm trying to use SimpleSocketServer (from logback-access) for remote logging of AccessEvent's. The problem I faced is following. When object get deserialized in SocketNode on line 64 it has no httpRequest (it's simply null). There is debugger dump of event:

event = instance of ch.qos.logback.access.spi.AccessEvent(id=932)
Thread-1[1] dump event
event = {
serialVersionUID: 866718993618836343
NA: "-"
NA_STRING_ARRAY: instance of java.lang.String[1] (id=914)
EMPTY: ""
SENTINEL: -1
httpRequest: null
httpResponse: null
requestURI: "/"
requestURL: "GET / HTTP/1.1"
remoteHost: "192.168.20.179"
remoteUser: null
remoteAddr: "192.168.20.179"
protocol: "HTTP/1.1"
method: "GET"
serverName: "jetty-test"
requestContent: ""
responseContent: ""
requestHeaderMap: instance of java.util.TreeMap(id=938)
requestParameterMap: instance of java.util.HashMap(id=939)
responseHeaderMap: instance of java.util.HashMap(id=940)
contentLength: 1288
statusCode: 503
localPort: 8080
serverAdapter: null
timeStamp: 1291621192027
}

So later this gives me NPE in AccessEvent.buildRequestHeaderMap().

I have following logback-access.xml for client

<configuration debug="true">
<appender name="SOCKET" class="ch.qos.logback.access.net.SocketAppender">
<remoteHost>logs.vfarm.loc</remoteHost>
<port>6000</port>
<reconnectionDelay>100</reconnectionDelay>
<includeCallerData>true</includeCallerData>
</appender>

<appender name="FILE"
class="ch.qos.logback.core.rolling.RollingFileAppender">
<File>/var/log/jetty/access.log</File>
<rollingPolicy
class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<FileNamePattern>access.%d

{yyyy-MM-dd}.log.zip</FileNamePattern>
</rollingPolicy>

<layout class="ch.qos.logback.access.PatternLayout">
<Pattern>combined</Pattern>
</layout>
</appender>

<appender-ref ref="FILE" />
<appender-ref ref="SOCKET" />
</configuration>

So logs are written locally (sucessfully) and sent over network to logs.vfarm.loc. On logs.vfarm.loc I have running SimpleSocketServer:

java -cp jetty-6.1.24.jar:\
servlet-api-2.5.jar:\
logback-access-0.9.26.jar:\
slf4j-api-1.6.1.jar:\
logback-core-0.9.26.jar \
ch.qos.logback.access.net.SimpleSocketServer 6000 access.xml

with following access.xml

<configuration debug="true">
<!--<appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
<File>access.log</File>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<FileNamePattern>access.%d{yyyy-MM-dd}

.log.zip</FileNamePattern>
</rollingPolicy>

<encoder class="ch.qos.logback.access.PatternLayoutEncoder">
<Pattern>combined</Pattern>
</encoder>
</appender>-->

<appender name="STDOUT"
class="ch.qos.logback.core.ConsoleAppender">
<encoder class="ch.qos.logback.access.PatternLayoutEncoder">
<Pattern>combined</Pattern>
</encoder>
</appender>

<appender-ref ref="STDOUT" />
<!-<appender-ref ref="FILE" />->
</configuration>

I think this issue is closely related to LBACCESS-6, but it's still reproducible.
