Question

In Java, I have created a class called Writer that extends
It is initialized with the followin, where bos is a ByteOutputStream:

this.internalWriter = new Writer(bos, Manager.defaultSize, new      Deflater(Deflater.DEFAULT_COMPRESSION, true));

When later I call

bos.writeTo(System.out);

Everything seems to work okay. But I noticed if I check out what bos is actually outputting by converting it to a byte array, it is always outputting these three bytes at the end of anything, and I don’t know why that would occur…any ideas? This is causing problems in my compression algorithm…

Those confusing three bytes are as follows:

[-27,2,0]

Writers in java treat everything like a String so what you’re seeing would be \r\n\0, which is a DOS newline sequence, followed by a string terminator.
