Java is not installed by default in Ubuntu 16.04.1
$ lsb_release -a
No LSB modules are available.
Distributor ID:	Ubuntu
Description:	Ubuntu 16.04.1 LTS
Release:	16.04
Codename:	xenial

$ java -version
The program 'java' can be found in the following packages:
  * default-jre
  * gcj-5-jre-headless
  * openjdk-8-jre-headless
  * gcj-4.8-jre-headless
  * gcj-4.9-jre-headless
  * openjdk-9-jre-headless
Ask your administrator to install one of them

How will it work "Exec=java"?
