I am running a java web application on tomcat on a docker container on Ubuntu on two machines. Both have the same OS version
Linux version 3.19.0-77-generic (buildd@lcy01-03) (gcc version 4.8.4 (Ubuntu 4.8.4-2ubuntu1~14.04.3) ) #85~14.04.1-Ubuntu SMP Mon Dec 5 11:19:02 UTC 2016
I have made sure that the war files are the same, the libraries loaded are of of the same version in both cases.
However, it gives a
Null Pointer Exception on machine and works fine on another.
How should I go about debugging this issue?
