> This issue mostly came up after a resolution to ACCUMULO-2668 that allows a byte[] to be passed directly to the underlying stream from the NoFlushOutputStream.
> The problem appears to be due to the BlockedOutputStream.write(byte[], int, int) implementation that recursively writes out blocks/buffers out. When the stream is passed a large mutation (128MB was sufficient to trigger the error for me), this will cause a StackOverflowError. 
> This is appears to be specifically with encryption at rest turned on.
> A simple fix would be to unroll the recursion.
