Hi Roger!
I didn't notice the message, so first commented in the Jira.
Would it make sense to also add a variant with the second argument of
type Supplier, so that it can be lazily calculated only if needed?
Something like:
public static <T> T nonNull(T obj, Supplier<T> nullDefaultSupplier) {
return (obj != null) ? obj : nullDefaultSupplier.get();
}
Sincerely yours,
Ivan

Java.lang.Objects contains a number of convenience methods to make it
easier to handle references that are null.
For example, toString(obj, nullDefault),
A new method is proposed to return the reference or a default value if
the reference is null.
static <T> T nonNull(T obj, T nullDefault);
Alternatives to the method name include
nonNullOrElse ( using the java.util.Optional name pattern) or
nonNullOrDefault
Please review and comment.
