> The method int CircularBufferInputStream.read() returns CircularByteBuffer.read() which a byte. 
> However it does not convert it to an unsigned byte, so byte values outside the range 0-127 will be sign-extended to a negative value.
> This is wrong, and can result in premature EOF.
> Note: this bug was reported by Sonarlint.
> Spotbugs does not appear to detect the bug.
