JUnit Rule TemporaryFolder arbitrarily throws an IOException

Solution
You should try disabling your anti-virus protection.
I was having same problem, and after disabling Kaspersky everything was working just fine.
Problem
I am facing a weird problem here... I have a JUnit implementing a few tests. This class looks like the following: ``` public class MyTest { @Rule public TemporaryFolder folder = new TemporaryFolder(); @Test public void myTest1() throws IOException { String destinationPath = folder.newFile("destination1.txt").getPath(); // Do things } @Test public void myTest2() throws IOException { String destinationPath = folder.newFile("destination2.txt").getPath(); // Do things } @Test public void myTest3() throws IOException { String destinationPath = folder.newFile("destination.txt").getPath(); // Do things } } ``` This test class used to work in my previous environment and still does in Continuum. Yet, when launching from Eclipse none, some, or all of the tests arbitrarily throw an `IOException` such as: ``` java.io.IOException: The system cannot find the path specified at java.io.WinNTFileSystem.createFileExclusively(Native Method) at java.io.File.createNewFile(File.java:883) at org.junit.rules.TemporaryFolder.newFile(TemporaryFolder.java:53) at MyTest.myTest2(MyTest.java:50) ``` I have the exact same problem running JUnit 4.9 or JUnit 4.10 ... How can I fix that so that it works properly?
