---------------------------
Here is the concerned code snippet (JaxWsServiceConfiguration.java.isWebMethod():
implInfo.getSEIClass() null check is after cls.isAssignableFrom(implInfo.getSEIClass()) threw an exception, I'm trying to move it ahead to solve my problem.

if ((wm != null && !wm.exclude()) || (cls.isInterface()
&& cls.isAssignableFrom(implInfo.getSEIClass())))

{ return Boolean.TRUE; }

if (method.getDeclaringClass().isInterface())

{ return hasWebServiceAnnotation(method); }

if (implInfo.getSEIClass() == null)

{ return hasWebServiceAnnotation(method) && !Modifier.isFinal(method.getModifiers()) && !Modifier.isStatic(method.getModifiers()); }

return implInfo.getSEIClass().isAssignableFrom(method.getDeclaringClass());
