DynamicProxy deserialization problem

xstream.toXML(accountManagerEJB) successfully creates accountManagerEJB.xml as follows;

<accountManagerEJB class="dynamic-proxy">
<interface>com.telus.eas.account.ejb.AccountManagerEJBRemote</interface>
<handler class="com.telus.provider.SynchronizedEJBInvocationHandler">
<name>telus-eca/ejb/stateful/AccountManager</name>
<interfaceClass>com.telus.eas.account.ejb.AccountManagerEJBHome</interfaceClass>
<arumentClasses>
<java-class>java.lang.String</java-class>
<java-class>java.lang.String</java-class>
<java-class>java.lang.String</java-class>
</arumentClasses>
<arguments>
<string>19171</string>
<string>ad26dou</string>
<string>OFFERM</string>
</arguments>
<initialContextFactory>weblogic.jndi.WLInitialContextFactory</initialContextFactory>
<providerURL>t3://wld3easeca:8382</providerURL>
</handler>
</accountManagerEJB>

However, deserializing accountManager.xml via xstream.fromXML( ) method results in the following exception when the parser encounters the accountManagerEJB closing tag;

com.thoughtworks.xstream.converters.ConversionException: Cannot convert type $Proxy23 to type com.thoughtworks.xstream.mapper.DynamicProxyMapper$DynamicProxy
