Eclipse Java auto complete changes exact matches to substring matches

Java->Editor->Content Assist, uncheck "show substring matches" in section "Sorting and Filtering"

Well, I feel silly answering my own question minutes after posting it, but I just figured out how to fix it, so here goes.

Load Preferences, then navigate to Java->Editor->Content Assist->Advanced. Check the Java Proposals check box.

I'm not that familiar with the different proposal types in these settings, but turning that one on fixed the problem.
