ADDITIONAL REGRESSION INFORMATION:
Dropdown above does not provide appropriate choice. The prior version it was working with was :

https://jdk8.java.net/archive/8u20-b14.html

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1)Download from https://jdk8.java.net/download.html Linux, JDK, 64-bit, tar.gz
2)Unpack to say /home/linux/Downloads/jdk1.8.0_20
3)In "/home/linux/Downloads" do "git clone https://github.com/artella-coding/Shen.java"
4)"cd Shen.java"
5)"export JAVA_HOME=/home/linux/Downloads/jdk1.8.0_20"
6)"./build"

Then you get error message above. If you do the same with "https://jdk8.java.net/archive/8u20-b14.html" there is no error
