Review comment:
I agree, that seems reasonable to me! Do you want to make the change in
the PR directly or create a JIRA?

Review comment:
Hello! For consistency with [how Schema caches the
hash](https://github.com/apache/avro/blob/42d81d70e7b9409d3b17fbcc9ea102876b45b945/lang/java/avro/src/main/java/org/apache/avro/Schema.java#L111),
what do you think about using Integer.MIN_VALUE instead of 0? Not a big deal,
except that all "zeroed" byte arrays will otherwise have hashCode 0 and be
recalculated every time.
