From 4370ff0998d3240cfda7745d08edbdd11703b984 Mon Sep 17 00:00:00 2001 From: Jean Chalard Date: Mon, 7 Apr 2014 22:32:06 +0900 Subject: Fix some flaky tests. In tests, we create many instances of LatinIME, but we never destroy them. That means we never close the dictionaries nor the handlers. This change calls onDestroy, which closes all dictionaries, and adds some code to finish the handlers.
