      With Fuse 7.7 or older versions, it works fine.
      The behavior was changed even cxf uses the same source code between Fuse 7.7 and Fuse 7.8:

      part of org.apache.cxf.common.util.ReflectionInvokationHandler.invoke()

              } catch (NoSuchMethodException e) {
                  for (Method m2 : targetClass.getMethods()) {
                      if (m2.getName().equals(method.getName())
                          && m2.getParameterTypes().length == method.getParameterTypes().length) {
                          boolean found = true;
                          for (int x = 0; x < m2.getParameterTypes().length; x++) {
                              if (args[x] != null
                                  && !m2.getParameterTypes()[x].isInstance(args[x])) {   //*** Please focus on this part!!!
                                  found = false;
                              }
                          }
                          if (found) {
                              ReflectionUtil.setAccessible(m2);
                              return wrapReturn(wr, m2.invoke(target, args));
                          }
                      }
                  }
                  throw e;
              }
      
      • With Fuse 7.8, "!m2.getParameterTypes()[x].isInstance(args[x])" ends up with "true", so could not go into the "wrapReturn()" code block, then throw e.
      • With Fuse 7.7, "!m2.getParameterTypes()[x].isInstance(args[x])" ends up with "false", so could go into the "wrapReturn()" code block.
