Description
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.

+1, oneByteBuf should be non-static, otherwise there may be issue for read() in multi threads.
Committed to trunk and branch-2. Thanks Sean Busbey for the contribution.
