From 0f14d3bf408d11549f861f22556c4740f9c13207 Mon Sep 17 00:00:00 2001 From: Robin Rosenberg Date: Sat, 28 Jun 2014 15:31:11 +0200 Subject: [PATCH] Try to fix intermittent test failure related to file timestamps Improve how tests do a "touch" operation on files. Instead of doing "f.setLastModified(System.currentTimeMillis)" open a Outputstream on the file and directly close it again. This makes this method rely only on one clock - the clock of the filesystem.
