Re: Compilation error when building Calcite package

[Maryann Xue]

I am working on mac, but have installed an oracle JDK:

java version "1.7.0_72"

Java(TM) SE Runtime Environment (build 1.7.0_72-b14)

Java HotSpot(TM) 64-Bit Server VM (build 24.72-b04, mixed mode)


I also once tried with JDK 1.8 before, but didn't get it right.



Thanks,

Maryann
