At Hacker news, users are talking about how the product's documentation could be formulated in a better way. Some users feel that the “Amazon's JVM is quite complex”. Users are also talking about Oracle offering the same service at a price. One user has pointed out the differences between Oracle’s service and Amazon’s service. The most notable feature of this release apparently happens to be the LTS offered by Amazon.
