Web-service client on Websphere throws NullPointer on method calling

We've been using
jaxws-spring
WebSphere 8.5.5.2
for our web-services interactions, and now we get stuck with such "cause" when we call any web-method on the client-side -
ServletWrappe E com.ibm.ws.webcontainer.servlet.ServletWrapper service SRVE0014E: Uncaught service() exception root cause appServlet:

Web-service client initialisation comes out with no any errors -
URL service_endpoint;
service_endpoint = new URL(endpoint);
service = new UDHandlersServiceImpl(service_endpoint, SERVICE_QNAME).getUDHandlersServiceImplPort();
NullPointerException occurs after calling any method of "service". And it doesn't even reach server side - because it doesn't have any logs there. Furthermore - such situation occurs only on the WebSphere - we deployed our client application on the Tomcat (server remained on websphere) and it worked fine. One more thing - SoapUI does not have any problems interacting with server side too.
We tried to switch classLoadings to parentLast for client application - with no success.
Also I can't even find sources for "org.apache.axis2.jaxws.message.databinding.JAXBUtils.getJAXBContext(JAXBUtils.java:445)". I googled it and didn't find this version of JAXBUtils. But even if i did, i think, it wouldnt be useful...
I hope someone can help us with that unobvious problem.
Thanks beforehand.
===== updated======
When we remove jaxb libraries from endorsed dir (or appServer/classes) problem seems to disappear but in case of arising webExceptions(faults) server throws
Caused by: java.lang.ClassCastException: com.ibm.xml.xlxp2.jaxb.JAXBContextImpl incompatible with com.sun.xml.bind.api.JAXBRIContext
at com.sun.xml.ws.fault.SOAPFaultBuilder.<clinit>(SOAPFaultBuilder.java:565)
at java.lang.J9VMInternals.initializeImpl(Native Method)
at java.lang.J9VMInternals.initialize(J9VMInternals.java:237)
and returns no answer to the client.

We've realized that our exceptions didn't contain 3 required methods -
//============required==================
public DocumentValidationException(String message, ErrorsBean errorsBean, Throwable cause) {
super(message, cause);
this.errorsBean = errorsBean;
}
public ErrorsBean getFaultInfo() {
return errorsBean;
}
public DocumentValidationException(String message, ErrorsBean errorsBean) {
super(message);
this.errorsBean = errorsBean;
}
//======================================
so, now it does.
And also we had some wrong target namespaces in it at the #WebFault annotations.
Here is the link with similar problem - https://www.ibm.com/developerworks/community/forums/html/topic?id=77777777-0000-0000-0000-000014076927#77777777-0000-0000-0000-000014083314

Google App add contact error?

In my GAE app there is the following line :
ContactsService myService=new ContactsService("app-name");
It compiled fine, but when run, it cause the following error :

I've included guava-r09.jar, so it has the "ImmutableSet", if I don't included guava-r09.jar, it will say :
Exception in thread "main" java.lang.NoClassDefFoundError: com/google/common/collect/ImmutableSet
What should I do ?

I found out why : don't need to include google-collect-*.jar, source of error.
