Bug#686222: libreoffice is not much "bloated" with Java...

[Dmitry Smirnov <onlyjob@member.fsf.org>]

Hi,

Just to notice that libreoffice is not as much in Java as it is in CPP nowadays.
Only some non-critical extra functionality is still requires Java.
However libreoffice preload JRE by default - you might be
pleasantly surprised how much faster libreoffice works with Java disabled by 
unticking "Use a Java runtime environment" in 

  Tools --> Options --> Java

See

Cheers,
Dmitry.
