Description

Lot's of places the fields are initialized to their default values, which is unnecessary verbose:

long value = 0L;
String str = null;

which is equivalent with:

long value;
String str;

And similarly the type specification can be omitted, as the compiler can calculate it automatically, so instead of

List<RangerPolicyConditionDef> conditions = new ArrayList<RangerServiceDef.RangerPolicyConditionDef>();

it is suffice to write:

List<RangerPolicyConditionDef> conditions = new ArrayList<>();
