Trivial - BUILDING.md directs to JDK 8

[Decar]

Code no longer runs under JDK 8.
Loading a saved game the VM fails because ByteBuffer.flip() doesn't exist.
JDK 9 resolved this issue because the method exists.
Here's a URL:

Buffer.flip should be there since https://docs.oracle.com/javase/7/docs/api/java/nio/Buffer.html#flip()

Last time I run it. I used

java version "1.8.0_131"
Java(TM) SE Runtime Environment (build 1.8.0_131-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)

Actually, forgive me...I've not installed Java for so long I'd not realised what happened. I'd installed the Java 10 SDK, but compiled it as JDK 8: This was the error I saw, and explanation: plasma-umass/doppio#497 (comment) I deleted 10 and installed with 9 and configured eclipse to compile and run as 9. Feel free to close this....I'm feeling old now.... Java 10, I first used 1.1 ;(
