Mahadev konar commented on ZOOKEEPER-402:
-----------------------------------------
ok this took me a while to figure out, since its a weird corner case. The c
library as it is supports NULL. So you can do a create of a node with NULL and
read it back. This will work. But the problem arises when you do a create with
the java client with data as NULL and read it from the c client. The other way
round works fine. The problem being that the java code serializes the NULL
buffer as -1 and the c code does it with serializing as 0 and does not handle
-1 on deserialization or serialization. We should fix the c recordio to handle
this. Ill upload a patch soon.
> zookeeper c library segfaults on data for a node in zookeeper being null.
