JDK can be easily varied in many environments. For example, some machines
in a cluster can use SUN JDK, and other machines can use open JDK or others.
Also, JDK 9 will be released in this year. This problem is about the trade-off
relationship between convenient and less mistake. If I should catch only one of
them, I'd like to choose less mistake.
