I wouldn't have thought so. If I do:
% cd /usr/ports/x11/nvidia-driver
% make pretty-print-build-depends-list
% make pretty-print-run-depends-list
This port requires package(s) "gettext-0.14.5 libiconv-1.9.2_1
linux-XFree86-libs-4.3.99.902_3 linux-expat-1.95.5_3
linux-fontconfig-2.1_3 linux_base-8-8.0_6 popt-1.7 rpm-3.0.6_10" to run.
There's no mention of java. I wouldn't say it definitively rules it out
though.
Are you sure that java wasn't left over from 4.X?
One thing to try is:
% pkg_info | egrep -i java
javavmwrapper-2.0_4 Wrapper script for various Java Virtual Machines
jdk-1.4.2p7_1 Java Development Kit 1.4.2
linux-sun-jdk-1.4.2.08_2 Sun Java Development Kit 1.4 for Linux
vnc-4.1.1 Display X and Win32 desktops on remote X/Win32/Java
display
% pkg_info -R jdk-1.4.2p7_1
Information for jdk-1.4.2p7_1:
% pkg_info -R linux-sun-jdk-1.4.2.08_2
Information for linux-sun-jdk-1.4.2.08_2:
Which shows that nothing on my system positively requires java (though
mozilla et al. use it). I doubt it's a browser as javac is the compiler
rather than the runtime environment (which has always seemed to crash at
irregular intervals for me).

*If* there are intermittent memory errors, then it could be that SETI
always happens to get them in the data it is dealing with, in which case
it might run perfectly happily but just produce the wrong results.
Memtest is dull, and stops you using your PC, but like Windows virus
scans, it seems like a necessary evil in this case.
