IndexOutOfBoundsException in PathImpl

I'm usign Hibernate validator 6.0.14. I'm getting a IndexOutOfBoundsException in my application using Spring Boot 2, Spring Data REST.
Probably the bug comes from Spring but, PathImpl method

raises a IndexOutOfBoundsException.

Debugging I see the nodeList is empty and of course when you do

the exception is raised.

This is your source code just to point out better where the problem is (line 373 in HV 6.0.14):

This is the stack trace of the exception:

I opened a bug in Spring Data REST (https://jira.spring.io/projects/DATAREST/issues/DATAREST-1342) as well.
