I don't think it's about the existence of null references, but how Java is using them. Null references can be a useful, e.g. Kotlin has converted them to be useful (with nullable types).

Using nulls in Java is mostly a choice on the part of developers; even if you can't migrate to a JVM-targeted language like Scala, you can still adopt practices like null objects [0].
