Use of CompositeByteBuf in NettyDataBuffer results in IllegalReferenceCountException [SPR-16351] #20898
Description
Abhijit Sarkar opened SPR-16351 and commented
DataBuffer write(DataBuffer... buffers) is supposed to "Write one or more DataBuffers to this buffer, starting at the current writing position" but it doesn't.
Consider buffer = "abc", slice = "def" and buffer.writePosition() = 3. buffer.write(slice) is supposed to produce abcdef but instead buffer becomes abcabc. The workaround is to use the write overload that takes a byte[], like so:
DataBuffer slice = buffer.slice(startIdx, length);
byte[] slice1 = new byte[length];
slice.read(slice1, 0, slice1.length);
buffer.write(slice1);
