public static byte[] getThreadLocalByteArray(int minimumLength) {
    return threadLocalByteArrayCache.get(minimumLength);
  }
Returns a byte array for use by the calling thread.
The returned byte array may be longer than minimumLength.
The byte array belongs to the calling thread but callers must
be careful to not call other methods that may also use this
byte array.
