服务端读取object时报Unable to read object larger than read buffer

默认的buffer2048 ,读取的时候报Unable to read object larger than read buffer异常，
当我把buffersize 扩大时，读取的结果为null,
不管怎么样都会走到这里
if (currentObjectLength <= 0) throw new KryoNetException("Invalid object length: " + currentObjectLength);
if (currentObjectLength > readBuffer.capacity())
throw new KryoNetException("Unable to read object larger than read buffer: " + currentObjectLength);
大家有遇到吗？
