Actually there was an Office like suite written in Java, e.g. Corel Office for Java.

JVM separation between computation and IO can be managed via classloaders and JAAS.

OpenOffice / staroffice were also partially Java based for a while if I remember correctly
They could use whatever JVM one has installed, but the dependency became optional and can be turned off (Tools->Options->LibreOffice->Advanced on LibreOffice). I keep it turned off as I don't have Java installed anywhere and probably I lose some features in the process, but I don't recall having any problems in normal use. I'm definitely not an advanced LibreOffice user though.
