Darrel Schneider commented on GEODE-2436:
-----------------------------------------
Geode does not support any instance of a java array as a key. Java arrays have
identity equals and hashCode which does not work as a Region key. We do
document that a class can only be used as a Region key if it implements equals
and hashCode.

> Key: GEODE-2436

> Project: Geode
> Issue Type: Improvement
> Components: regions
> Reporter: Hitesh Khamesra
>
> Geode doesn't handle byte[] as key. "byte[]" doesn't implement
> hashcode/equals method, it just returns native hashcode. Because of that
> following code returns null for key k2;
> {code}
> Cache c = CacheFactory.getAnyInstance();
>
> Region region = c.getRegion("primitiveKVStore");
> byte[] k1 = new byte[] {1,2};
>
> region.put(k1, k1);
> byte[] k2 = new byte[] {1,2};
> System.out.println(">>>>>>>>>> " + region.get(k2));
> {code}
