JAXRPC ws-client generation failure with WL10.3

Question

Hi all.
My deep apologies for crossposting; this question was posted first to "WebLogic Server - Upgrade" forum and just later I found this webservices related topic.
I'm copying it as it for for the sake of convenience.
I'm facing a problem to generate web-service client with WL-10.3, while WL-9.2 works pretty fine with this WSDL.
My ANT task is:
<clientgen
type="JAXRPC"
wsdl="${WSDL}"
destDir="${DESTDIR}"/>
In case type is set to JAXWS, generation succeeds. However, if I set it to JAXRPC (I need to enable multirefs to support closed graphs), the generation fails with exception:
weblogic.wsee.tools.WsBuildException: weblogic.descriptor.DescriptorException: Failed to marshal: weblogic.j2ee.descriptor.JavaWsdlMappingBeanImpl
at weblogic.wsee.tools.anttasks.ClientGenFacadeTask.execute(ClientGenFacadeTask.java:235)
at weblogic.wsee.tools.anttasks.ClientGenTask.execute(ClientGenTask.java:358)

at weblogic.descriptor.internal.MarshallerFactory.<init>(MarshallerFactory.java:48)
Are there any known limitations/issues regarding JAXRPC support for WL-10.3?
Is there any workaround for this problem?
Greatly appreciating any inputs
Sincerely
Jabb

Updates.
Meanwhile I found that the mentioned failure is caused due to inner calls to ClassLoader.getResources() searches for "META-INF/binding-file.ser" and "META-INF/binding-mapping-file.ser" calls which returns empty results. However these files were succesfully created in directory pointed by destDir attribute. I added the destDir dir to taks's classpath:
<clientgen
type="JAXRPC"
wsdl="${WSDL}"
destDir="${DESTDIR}">
<classpath>
     <pathelement location="${DESTDIR}"/>
</classpath>
</clientgen>
and this faulire was gone, but new appeared:
