Java8

Why Java 8 is not dead

• Because Java 9 breaks things
• Because Java 10 breaks more things
• Because Java 11 breaks even more things
• Because Java >=12 will surely break more of the stuff that has been working perfectly for years

And the cost/benefit relation of moving along Oracle's ideas seems not worthwile.
