Java Play Mustache NPE Error

We get a mustache game error in production (amazon linux EC2 AMI), but not in development (MAC), and we tried updating jvm using jdk instead and moving from the tomcat deployment model to our development environments as much as possible, but nothing works. Please any help would be greatly appreciated. We have a lot of common code in java and javascript using mustache, and it would be very important to rewrite everything if we had to truncate the mustache on the java side.

The problem seems to be related to threadlocal. In Prod, according to my logs, the session is initialized with the main thread.
