Petr Kremensky commented on WFCORE-1048:
----------------------------------------

I have two Virtual Windows servers available. One is w2k8 the other is w2k12.

I found there is a difference in  the granularity of measured time for these (currentTimeMillis() [javadoc|http://docs.oracle.com/javase/7/docs/api/java/lang/System.html#currentTimeMillis%28%29]):
{code:java}
SimpleDateFormat format = new SimpleDateFormat("yyyyMMddHHmmssSSS");
for (int i = 0; i < 100; i++) {
    System.out.println(format.format(new Date()));
}
{code}

w2k8 - EmbeddedServerFactorySetupUnitTestCase pass locally

Adding more output to the test I can see that it really tries to create directory with the same timestamp more than once. We have to either change the way of how the name of temp root directory is generated, or add some waiting between the tests.

Following solves the issue for me locally:
{noformat}
public class EmbeddedServerFactorySetupUnitTestCase {
...
     @Before
-    public void createEmbeddedRoot() {
+    public void createEmbeddedRoot() throws InterruptedException {
+        Thread.sleep(1L);
         embeddedRoot = new File("target/embedded-root").getAbsoluteFile();
{noformat}
