In my project I found the library which brings Jackson core 2.6.5 and it is
used in conjunction with the requested Jackson scala module 2.5.3 wanted by
spark 2.0.0 preview. At runtime it's the cause of exception.
Now I have excluded 2.6.5 using sbt but it could be dangerous for the other
library.
Why this regression to Jackson 2.5.3 switching from 2.0.0 snapshot to preview ?
Thanks

Hi,
developing a custom receiver up today I used spark version "2.0.0-SNAPSHOT" and
scala version 2.11.7.
With these version all tests work fine.
I have just switching to "2.0.0-preview" as spark version but not I have
following error :

I see that using 2.0.0-SNAPSHOT the jackson core version is 2.6.5 ... now 2.6.1
with module scala 2.5.3.
Thanks,
Paolo.
