Hey there I can't install LanguageTool 2.8 on LibreOffice

Hey there I can't install LanguageTool 2.8 on LibreOffice with French Menus and Dictionaries.

Here is the version of LibreOffice I'm using:
Version: 4.2.7.2
Build ID: 420m0(Build:2)

I'm using this software on on Ubuntu 14.04 LTS:

I just checked with LibreOffice 4.3.5.2 and it works fine.

LanguageTool relies on Java7. What version of Java does LibreOffice use?
