java registry settings

Menu Tools/Options.../LibreOffice/Advanced/Java Options
"[X] Use a Java runtime environment" allows to enable/disable Java.

Java settings can be preconfigured using a"javasettings_Windows_x86.xml"
in \share\config, for example:

<?xml version="1.0" encoding="UTF-8"?>
<java xmlns="http://openoffice.org/2004/java/framework/1.0"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
        <enabled xsi:nil="true"/>
        <userClassPath xsi:nil="true"/>
        <vmParameters xsi:nil="false">
                <param>-Xms64M</param>
                <param>-Xmx512M</param>
        </vmParameters>
        <jreLocations xsi:nil="true"/>
        <javaInfo xsi:nil="false" vendorUpdate="2013-05-02" autoSelect="false">
         [...]
        </javaInfo>
</java>

if a shared java setting is present, LO will write a dummy (?)
"javasettings_Windows_x86.xml" to \user\config:

<?xml version="1.0" encoding="UTF-8"?>
<!--This is a generated file. Do not alter this file!-->
<java xmlns="http://openoffice.org/2004/java/framework/1.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<enabled xsi:nil="true"></enabled>
<userClassPath xsi:nil="true"></userClassPath>
<vmParameters xsi:nil="true"></vmParameters>
<jreLocations xsi:nil="true"></jreLocations>
<javaInfo xsi:nil="true"></javaInfo>
</java>

in an enterprise environment users maybe should not be able to change 
preconfigured java settings. but at the moment a user can change it.
the changed "javasettings_Windows_x86.xml" is written to \user\config
and replaces the shared java settings.

checkbox "[X] Use a Java runtime environment" sets
<enabled xsi:nil="false">true</enabled> or
<enabled xsi:nil="false">false</enabled>
inside "javasettings_Windows_x86.xml".

there is also a registry entry
"org.openoffice.Office.Java/VirtualMachine/Enable" but changing it's value
seems to have no effect.
