Doug Cutting commented on AVRO-2050:

Arrays.fill() would be simpler than coding the loop yourself and perform
similarly.
A more optimized implementation could use System.arraycopy(), which is native
code, but that's perhaps overkill.

> Java's {{ArrayList}} implementation clears all Objects from the internal
> buffer when the {{clear()}} method is called. This allows the Objects to be
> free for GC. We should do the same in Avro
