[Building Sakai] Resources tool on Sakai 10

[Matthew Jones]

I'd first try setting the option -Djava.util.Arrays.useLegacyMergeSort=true or
upgrading to 1.7.0_65. (java -version) where this might be fixed.

If that doesn't fix it, there was some discussion about it on KNL-1247 but
we couldn't reproduce it. And the fix on the ticket didn't sort the smart
sort the same way as the current method sorts and it doesn't look like it
was ever followed up on.
