My Play 2.1.1 project uses SBT 0.12.3, and when compiling it on my dev machine everything is fine, I get no errors, and the application works without any problems. When I try to compile it on the EC2 instance used for testing, I get an ultra-low error message. The only possible difference between the two environments is that I have java 6 (1.6.0_45) on my dev machine and java 7 (1.7.0_19) on EC2, but I cannot currently change any of them. Have you ever seen something like this? What could it be? Thanks!
