java.lang.stackoverflow error when creating a REST Connector



While trying to create a REST connector on a elasticsearch REST API provider, you test the REST API which returns a correct JSON response.

However, the connector creation fails before creating the different objects (for example: interface classes, data objects and data page) with an error message in the log file.

Steps to Reproduce

1. Start Wizard, enter URL and perform all steps by saving responses. 
2. Rule generation fails with stack overflow exceptions.

Root Cause
