Update code checks both non-null and instance of a class in java.naming module
classes.
The checks and explicit casts could also be replaced with pattern matching for
the instanceof operator.
For example:
The following code:
return (obj != null &&
obj instanceof CompoundName &&
impl.equals(((CompoundName)obj).impl));
Can be simplified to:
return (obj instanceof CompoundName other) &&
impl.equals(other.impl);
