java.io.StreamCorruptedException: invalid stream header

Hello,
I get the following exception when I try to retrieve my serialized collection from a remote service, via httpInvoker client. The remote invocation seems to work the first time, exception is thrown the second time. I am using spring-2.5.5.jar. the server application is on Tomcat. Protocol used on server is https. I am using jdk1.6.0_07. Am I using this incorrectly.


Here is my applicationContext.xml for client

	<bean id="myHttpClient" class="com.dsainc.pcf.remoting.http.HttpClientFactoryBean">
  		<property name="username" value="user" /> 
  		<property name="password" value="password" /> 
  		<property name="authenticationHost" value="server.com"/>
	</bean>	


	<bean id="acqPlanServiceHttpInvokerProxy" 		class="org.springframework.remoting.httpinvoker.HttpInvokerProxyFactoryBean">
		  <property name="serviceUrl" value="/acqplan/acqPlanService.htm" />
		  <property name="serviceInterface" value="com.dsainc.pcf.remote.acqplan.AcqPlanService" /> 
		  <property name="httpInvokerRequestExecutor" ref="requestExecutor" /> 
	</bean>
 
 
	<bean id="requestExecutor" class="org.springframework.remoting.httpinvoker.CommonsHttpInvokerRequestExecutor">
 		<property name="httpClient" ref="myHttpClient"/>
	 </bean>

afterPropertiesSet method of HttpClientFactory

public void afterPropertiesSet() throws Exception {
    	System.out.println("httpClient after Properties set ");
	        if ((username == null) || (password == null)) {
            throw new IllegalArgumentException(
                    "You must set the username, password and "
                            + "authenticationHost properties");
        }
        MultiThreadedHttpConnectionManager mt = new MultiThreadedHttpConnectionManager();
        
        httpClient = new HttpClient(mt);
       
        System.out.println("httpClient created");        
        
        httpClient.getHostConfiguration().setHost(authenticationHost, 443, "https");
        
        System.out.println("host Url " + httpClient.getHostConfiguration().getHostURL());
        
        httpClient.getParams().setCookiePolicy(CookiePolicy.BROWSER_COMPATIBILITY);

        System.out.println(httpClient.getParams().getCookiePolicy());
        
        httpClient.getParams().setAuthenticationPreemptive(true);

        System.out.println("setting authentication premptive ");
        
        Credentials credentials = new UsernamePasswordCredentials(username, password);
        
        AuthScope as = new AuthScope(authenticationHost,0,authenticationRealm);
        
        httpClient.getState().setCredentials(AuthScope.ANY, credentials);
        httpClient.getState().setCredentials(as, credentials);
       
        httpClient.getParams().setConnectionManagerTimeout(60000);
        
        System.out.println(httpClient.getState().getCredentials(AuthScope.ANY));
  }

test to access remote service

	// login to remote application via the myHttpClient bean

             // access service on remote host
	List<CabinetDO> cabinets = (List<CabinetDO>)acqService.getCabinets(Integer.valueOf("2009"),"USER", "ORGID");
	if (cabinets != null) {
		System.out.println(" Cabinet size " + cabinets.size());
		System.out.println(" cabinet 1 " + cabinets.get(0).getCabinetName());
	}	else {
		System.out.println(" returned  null");
		return;
	}

	
	//second trip by httpInvoker to get Cabinets
	cabinets = (List<CabinetDO>)acqService.getCabinets(Integer.valueOf("2009"),"USER", "ORGID");

system output and stack trace of exception
