Load Generator Not Executing the script as expected

Hi,
I have a very peculiar problem, I have developed a java code and tested with 6.9 and also tested locally with 6.5.1. In the local load generator I tested with 100 users with 10 iteration and it works without any problem. I see that it is using java version 8.112 . When I run from the load generator, some part of the java code is failing and not returning any values. What could be the problem, i noticed that the generator also have the same version of java as the local host generator. How to solve this problem.
