I can not get Validators

when I use ValidatorsApi to get the validators, I get null. My code is :
`Validators validators = ValidatorsApi.getValidators();
System.out.println(validators.getValidators().get(0).getPower());`

Start by tracing ValidatorsApi.getValidators() and the Validators response handling in the Java driver. Reproduce the reported call and inspect the returned value and any available response details; done means identifying why the validators result is null and adding a regression check or clear documented behavior.
