Hi,
I'm getting a NPE at DecoderContext.decodeWithChildContext, but I'm not able to reproduce it at will..
The query works for some time, and suddenly starts to fail erratically (some times it fails some times it doestn't).
I tried to find if it was a concurrency type of issue, tried to syncronize access but didn't mattered.
Also happens with many version of the server (3.6.x, 4.0.x).
Tried changing the driver version (now running 3.11.0-rc0) but also didn't mattered.
Anything else you think I can try to corner it?
Regards,
Juan.
