[SQL] [TEST] [MINOR] Follow-up of PR #6493, use Guava API to ensure Java 6 friendliness

This is a follow-up of PR #6493, which has been reverted in branch-1.4 because it uses Java 7 specific APIs and breaks Java 6 build. This PR replaces those APIs with equivalent Guava ones to ensure Java 6 friendliness.

cc andrewor14 pwendell, this should also be back ported to branch-1.4.
