Opening a page with "Hello Soy Portlet" causes a StackOverflowError during portlet render.

This regression is caused by LPS-76970:

• We replaced JSON deserialization/serialization with a recursive method
• The new code don't work in case of having a cycle (Map with a child that includes a reference to the parent Map)

Steps to reproduce

1. Create a new page of type "Full Page Application" with application "Hello Soy Portlet"
2. Open the new created page
   • Expected behavior: page is displayed successfully
   • Wrong behavior: page is not displayed and a StackOverflowError is thrown in log file
