Any idea about processing java.lang.Object failed?

[hunts]

By my RESTful service, i met following issue which casue the model-schema result in missing many models.

converter.ModelPropertyParser - processing class class java.lang.Object 17:46:50.575 [http-8080-6] DEBUG c.w.s.converter.ModelPropertyParser - processing method public final void java.lang.Object.wait() throws java.lang.InterruptedException 17:46:50.575 [http-8080-6] DEBUG c.w.s.converter.ModelPropertyParser - processing method public java.lang.String java.lang.Object.toString() 17:46:50.575 [http-8080-6] DEBUG c.w.s.converter.ModelPropertyParser - processing method public native int java.lang.Object.hashCode() 17:46:50.575 [http-8080-6] DEBUG c.w.s.converter.ModelPropertyParser - processing method public final native java.lang.Class java.lang.Object.getClass() 17:46:50.575 [http-8080-6] DEBUG c.w.s.converter.ModelPropertyParser - inspecting null 17:46:50.575 [http-8080-6] DEBUG c.w.s.converter.ModelPropertyParser - skipping class

Hello, is there anyway you can provide me with any more information? Possibly the class that is missing?
