WebThe Netty 4.1 ByteBuf would automatically expand in capacity as needed when written to, until a certain maximum capacity. The new Buffer API no longer do this, and no longer have a capacity and max-capacity distinction. Code should instead allocate properly sized buffers (the size argument is now mandatory), and/or call ensureWritable () as needed. WebDec 29, 2024 · Motivation Recent optimization netty#9765 introduced a bug where the native indices of the internal reused duplicate nio buffer are not properly reset prior to using it to copy data during a reallocation operation.
