Hi,
FYI: LanguageTool requires Java 7, which won’t get any further security updates from Oracle, as its successor (Java 8) has been released a year ago. So future versions of LanguageTool will require Java 8, starting with LanguageTool 3.2, to be released 2015-12-28.
You can have a look at our development roadmap at Roadmap - LanguageTool Wiki
Regards
Daniel
