      When JsonPathExpression#eval method is called with a JsonNode context that defines properties SECRET or WORKFLOW (which are reserved keywords) then following exception occurs for the "Recursive descent" operator (https://github.com/json-path/JsonPath#operators):

      ..property

      java.lang.ClassCastException: class org.kie.kogito.expr.jsonpath.WorkflowJacksonJsonNodeJsonProvider$$Lambda$399/0x00000008002fd440 cannot be cast to class com.fasterxml.jackson.databind.node.ObjectNode (org.kie.kogito.expr.jsonpath.WorkflowJacksonJsonNodeJsonProvider$$Lambda$399/0x00000008002fd440 and com.fasterxml.jackson.databind.node.ObjectNode are in unnamed module of loader 'app')

      The reproducing test case is added as part of KOGITO-7127, but disabled for now. Needs to be enabled as part of the fix.
