Xianda Ke commented on CRYPTO-86:
---------------------------------

Properties instance was used only in 
PositionedCryptoInputStream.getCipherState().
{code}
                cipher = CryptoCipherFactory.getInstance(getCipher()
                        .getTransformation(), getCipher().getProperties());
{code}
agree with [~s...@apache.org]. Since PositionedCryptoInputStream itself has 
Properties parameters, there is no need to hold the Properties reference in 
CryptoCipher.

> The CrytoCipher implementations currently store a reference to a Properties 
> instance.
> However it does not appear to be used by the class except to create a new 
> instance of the class.
> It looks like the field could be dropped entirely.
