ov-java.cc-tst fails on octave 4.0.0 on lubuntu 14.04

[Tatsuro MATSUOKA]

I have built octave 4.0.0 on Ubuntu 14.04 LTS (amd64) and Lubuntu 14.04.

On Ubuntu 14.04 LTS (amd64),make check shows no FAIL after workaround 
$ export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libGL.so.

On  Lubuntu 14.04 (32bit), I have met the following FAIL.
libinterp/octave-value/ov-java.cc-tst ....................... PASS      4/5   
                                                                  FAIL    1
