build failure running 0.9.0-SNAPSHOT using JDK 9

[lwhite1]

I used the instructions from Getting Started.

git clone git://github.com/brianfrankcooper/YCSB.git
cd YCSB
mvn clean package

and got:

Thanks for the heads up! Unfortunately, we don't currently support building with jdk9.

Can you try building with jdk8 or jdk7?

Alternatively, our 0.8.0 release should be published shortly. Depending on which datastore you want to test with, you could rely on the binary artifacts from that release.

Closing this since it references 0.9.0. The tracking of JDK 9 support will be here: #705
