Java problem

[LeeUnd]

Can't seem to find any help for this

I am trying to install the 'Meow' Gnome menu manager, found at: github. However, when I load it in the GDebi Package Installer (using the Ubuntu download file), I get the following error messages when Lintian runs:

Lintian finished with exit status 1

I have Java v8 installed:

java -version
java version "1.8.0_111"
Java(TM) SE Runtime Environment (build 1.8.0_111-b14)
Java HotSpot(TM) Server VM (build 25.111-b14, mixed mode)

And I am running Ubuntu 14.04, Gnome Shell 3.10.4.

Anyone have any ideas of what is wrong here?
