Kevin Risden commented on KNOX-1230:
------------------------------------
[~lmccay] - Can you share what some of the symptoms of this would be? We are
looking at some sporadic 401 errors under high load with Knox. We haven't found
the root cause yet (or close enough to even speculate). I looked through the
patch and it wasn't clear what this could cause.

> We have had some thread safety issues in both our crypto and dispatch
> machinery for what appears to be have been a long time - if not forever.
> This patch locks down access to the DefaultKeystoreService, synchronizes the
> creation and initialization of dispatches and removes most of the state in
> the ConfigurableEncryptor class. It also moves the responsibility of query
> string encryption and decryption into the
> SecureQueryEncrypt/DecryptProcessors themselves rather than leveraging the
> CryptoService by creating member variables for the required
> ConfigurableEncryptor.
