From 2c23efcdb5bf7e055caa166e56cfdd50011f02df Mon Sep 17 00:00:00 2001 From: Jesse Wilson Date: Mon, 31 Aug 2009 10:52:23 -0700 Subject: [PATCH] Update prefs to Harmony r772995. Notable changes: - exception handling has changed to cleanup more reliably - calls to Collection.toArray() size the array properly - lots of style tweaks (rewrapping Javadoc, reintending wrapped code, whitespace) - new PrefsTester class ensures tests store prefs in the tmp directory Squashed commit of the following: commit 2157269d8ed39ccb8a71d735c12bbabcfd548243 Merge: d287282 97818bf Author:
