Jason Brown updated CASSANDRA-13949:
------------------------------------
Attachment: 13949.png
I tried to reproduce using your attached scripts (very handy, thanks!) on a
local running instance of casandra, but was unable to reproduce the
{{NullPointerException}}. I did however, get a very curious output in the
{{value}} field: at four point in the large json blob, there are a few Kb of
printed null characters {{\x00}}. See the attached image. I hexdump'ed your
insert.cql and it looked legit (no stray characters).
I then checked our json libs, and they are quite old - jackson*-1.9.2,
committed in 2011! The latest jackson jars are version 1.9.13 on maven central
(from 2013). I naively replaced the jars in lib/, and I didn't get the null
character output anymore.
Can you try simply replacing the jars and see if the NPE stops occurring? If it
does, then I'll create a more formal patch, run tests, and so on.
