wuyiyun commented on ZOOKEEPER-2973:
------------------------------------

I met this problem too, while i use open ssl capability on zookeeper server and zookeeper
client. while i close ssl capability and will not cause this problem.

you can modify source of BinaryInputArchive like below and find what

public String readString(String tag) throws IOException {
 int len = in.readInt();
 if (len == -1) return null; 
 
 checkLength(len);
 byte b[] = new byte[len];
 in.readFully(b); 
 String tobeReturnString = new String(b, "UTF8");
 LOG.info("####################Just readString String's lengh="+len+" and this string is:"+tobeReturnString);
 
 return tobeReturnString;
 }
 
 static public final int maxBuffer = Integer.getInteger("jute.maxbuffer", 0xfffff);

public byte[] readBuffer(String tag) throws IOException {
 int len = readInt(tag);
 if (len == -1) return null;
 checkLength(len);
 byte[] arr = new byte[len];
 in.readFully(arr); 
 String tobeReturnString = new String(arr, "UTF8");
 LOG.info("####################Just readBuffer String's lengh="+len+" and this string is:"+tobeReturnString);
 return arr;
 }
