In my case, this was due to Application Module configuration, in ADF application we have two configuration.

  1. AMLocal
  2. AMShared

For local configuration, in Pooling and Scalability, there is Maximum Pool Size is 4096 but for sharing it is only 1
I am not getting why this is so, then I have set Maximum Pool Size for shared configuration to 4096 and it is working.

  1. I am not sure what this solution has to do with the error.

    I've seen this error many times when one of the fresh developers in our company forgets the faces part of the request url or whatever is configured to trigger the javax.faces.webapp.FacesServlet servlet.
