[Libreoffice] javaldx /proc test in ooinstall

Hi all,

I'm getting annoyed by the /proc test in ooinstall

$ gmake install
Installing in /usr/local...
. ./*[Ee]nv.[Ss]et.sh && \
ooinstall "${prefix:-/usr/local/LibreOffice}"
The installer cannot work without javaldx running, which requires /proc to be mounted at 
/home/ftigeot/Projects/LibreOffice/bootstrap/solenv/bin/ooinstall line 17.

If I just remove the test, the installation goes fine...

What is this javaldx thing ? Is there a reason this test cannot be removed
for all platforms ?
