> A common optimization in the io classes for Input/Output Streams is to save a single
length-1 byte array to use in single byte read/write calls.
> CryptoInputStream and CryptoOutputStream both attempt to follow this practice but mistakenly
mark the array as static. That means that only a single instance of each can be present in
a JVM safely.
