-----------------------------------
Reporter: Gabor Szadovszky (was: Zoltan Ivanfi)
> Type.hashCode() takes originalType into account but Type.equals() does not

> Project: Parquet
> Issue Type: Bug
> Reporter: Gabor Szadovszky
>
> If two Type instances are equal according to equals() but have different
> logical types, then both of the following cases are possible:
> * The two instances may accidentally have the same hash, which is consistent
> with the equals() method but is pure coincidence and has a very low
> probablility.
> * The two instances may have different hashes and end up in different buckets
> of a hash map, leading to a situation where we can't find a value in the hash
> map despite that it's equals() would return true.
