PartitionMetadata hasLeader

Hello Apache Kafka community,

Scala API had hasLeader method in PartitionMetadata of MetadatResponse. I
see new Java API does not have such method and there's no javadoc on the
class. Can somebody please explain - will leader reference be null or
something when partition has no leader? Why not encode this into a method
like hasLeader?

Kind regards,
Stevo Slavic.

Correction, leader was an Option, and I guess Optional cannot be used yet
because Java language level compatibility is too low. What a mess, Java and
Scala in codebase, and even new code being written in old Java.
