Single Item Producer-Consumer. Which datastructure can I use in Java?

I want have a Producer Consumer Problem where only the newest Item shall
be consumed. This problem may have a different name, but I couldn't figure
it out!
The producer thread(s) produce elements in a non-blocking fashion by
overriting any old items. The single consumer thread should wait for an
element to be created and consume it.
I thought about using a blocking queue but the java implementation does
not allow for overriding old elements. A circular buffer (like from the
commons libary) doesn't work either because its not blocking for the
consumer.
Is there a datastructure that serves this purpose or do I need to find a
better way?
It might also be possible to solve this with low level synchronization
tools like locks but I couldn't figure out how to do it.
