Why OpenJDK ? Why not Oracle Java JDK
Oracle Java is not free anymore!. We need to buy subscription for its usage. Typically for Java SE Desktop Subscription you might have to pay minimum 2.5$ per named user profile per month. And minimum of 25$ per processor (volume 1-99).

On the other hand, OpenJDK is free for all and you don't have to pay single penny!. If you don't want you buy Oracle Subscription and still want to use Java for free in all your Production Systems then OpenJDK is the right choice for you.
