Set JRE in LibreOffice

hi robert and girvin.
i know that base is not only the feature that needs java, as you
mentioned report builder and mediawiki also need java.
but i ment that the component that needs java is only base.
for example: i dont think writer needs java at all.
openoffice is more depending on java, even for saving files as xml and
also using different wizards like letter, web page, agenda,
presentation, fax.
but libreoffice supports all these features without java thanks God.
do you know how many percentage of libreoffice codes is written in java?
thank you God bless you all!
