Patrick Hunt commented on ZOOKEEPER-240:
----------------------------------------
Jute generated toString methods rely on CSVOutputArchive which in turn relies
on Jute's Utils.java. the toCSVBuffer doesn't check for null buffer, which it
should.
Note: if you fix this (add null check to toCSVBuffer) please be sure to review
the rest of the code in Utils.java for similar problem(s).
