NoSuchMethodException for an accessible method

I am using Open KM framework for my application. It's weird to see that at times I get a NoSuchMethodException in my code for a method that is available. As soon as I start getting this exception, it keeps repeating until I restart the server (Jboss7). After restarting, this will run the file up to some point and then again this exception will happen and continue.

Can anyone help with this?

My exception trace

I've also added some other traces to see what the calling class and expected method are. These are the results

19:34:10,719 INFO  [stdout] (http--192.168.1.62-8080-2) Trying to fetch method ========      create from class : interface com.openkm.ws.client.document.OKMDocument

This is the result of getMethods from the called method endpoint class

19:34:10,721 INFO  [stdout] (http--192.168.1.62-8080-2)  Method Name :: create
19:34:10,721 INFO  [stdout] (http--192.168.1.62-8080-2) Parameters.... java.lang.String

19:34:10,721 INFO  [stdout] (http--192.168.1.62-8080-2) Parameters.... [B

      

        
        
        
      

    

As you can see, the calling signature

create(String, com.openkm.ws.client.document.Document, byteArray)

      

        
        
        
      

    

and the target class also has a method with the same signature, but still from time to time I get this NoSucnMethodException and as said after it appears, then it keeps coming until I restart the server.

Any help ...
