  The issue occurs because of a design change in WebSphere
  Process Server and WebSphere Enterprise Bus V7. The SCA
  related module began to process interactions in a new way that
  uses a wrong interface for heritage applications. As a result,
  the exception occurs.
  

Problem conclusion

• A fix that accommodates the design changes will be included in
  an IBM BPM V8.5.6.0 cumulative fix.
